Ideally, a new pair of shoes should be comfortable and fashionable. However, you may find a lot of options in footwear shops that meet these 2 criteria, but at the same time their quality is so bad that they won’t last long. We decided to find out what things you should pay attention to in order to choose a really high-quality pair.
Check the shoes for smudges and glue marks.
Manufacturers often use glue to stick together different parts of the shoe. If the glue is of high quality and the work is done properly, the pair will last a long time. However, small glue drips in the spots where parts meet or traces of glue on the surface indicate that you are looking at low-quality shoes and that there were issues during production.
When a part of the shoe, its sole or insole, comes off a bit, it means the shoemaker probably used bad or expired glue, and this pair will fall apart quickly.
Examine whether the pair is symmetrical.
Quality shoes in a pair should be symmetrical, and any differences between the right and left shoes most likely indicate a defect. To check this, you need to put the soles of both shoes together and see if they match in length and width.
It’s also worth putting the pair on the floor to understand whether the height and outline of the upper edge of the heel are symmetrical. If the soles are painted in different colors, check whether the paint is within the borders of the sole and whether the pattern matches. Gross irregularities in symmetry indicate that the manufacturer didn’t pay much attention to quality.
Check the seams carefully.
Any uneven or diverging seams make shoes look not that good. This happens if the manufacturer used too thin threads or the work was done poorly. As a result, such a pair will fall apart much faster. It’s also necessary to check the uniformity of stitches and the evenness of the seam itself.
If its line is curved or zigzag-looking, this means that the shoes you’re looking at are of poor quality and will lose their appearance in a couple of months. And zigzag-looking stitch is often used to hide the imperfections of the stitching.
Examine the heels.
The heel must be firmly attached to the sole and not wobble. It’s necessary to look at the shoes from the side. In good quality pumps, the high heels are positioned exactly under the center of the heel and touch the ground at a slight incline.
It’s worth looking carefully at the heels from behind – any deviation of the heels from the angle of 90⁰ indicates a defective product. Moreover, these shoes are simply dangerous to wear – this may lead to ankle injuries.
Loose eyelets are a bad sign.
Any metal or plastic parts on the shoe (especially those that come into contact with the skin) should be tightly fastened. Thus, it’s worth carefully examining the eyelets for laces. Although this defect is quite rare, it can lead to wearer’s injury.
You should also check how well any embellishments are attached to the shoe. If they fall off at one point, the pair won’t look good anymore.
Carefully inspect the inside of the shoe.
Some manufacturers save on the training of workers and don’t calibrate equipment before the production of a new product line. As a result, shoes, boots and sneakers may have seemingly insignificant defects such as wrinkles and creases. If these defects are small, they won’t cause much trouble to the wearer. But large creases can rub the skin while walking, which will lead to abrasions and blisters on the feet.
Examine the insoles.
Even if a shoe looks perfect from the outside, you need to scrutinize it from the inside too. If the insoles show small wrinkles and creases, this pair is likely to be uncomfortable to wear. In addition, you should carefully feel the insoles to make sure that there are no bubbles on them.
Another important thing is that there must be cushioning between the insole and the sole, especially in the toe and heel area. Otherwise, a long walk in these shoes will make not only your feet and legs sore, but also your back.
Check how the shoes smell.
Low-quality and cheap shoes often have a strong chemical odor. It’s best to refrain from buying this pair. But if shoes or boots exude the scent of leather, polish or wood, you’ve found the shoes of high quality.
Take a photo of the shoes.
Of course, shoes made of synthetic materials can also be of high quality, especially when it comes to sports models. But good shoes should ideally be made of leather. They are softer and fit better on the foot, which means they will be much more comfortable to wear.
However, the quality of leather also varies. Often, manufacturers don’t mention the type of leather they use to make shoes in order to keep costs down. To determine the quality of the product you are holding in your hands, you need to take a photo of the shoes and enlarge the image. If you can see pores on the leather, you can safely buy the shoes.
Bend the shoe a little bit.
You don’t need to knead your shoes too much, but you can bend the shoe slightly to see how flexible the sole is and whether it remains attached to the upper part when moved. In addition, it’s worth pressing the sides of the shoe a little bit. Throughout the day, our feet usually increase in size a little, so a quality pair should adapt to these changes.
Check how your shoes sound.
Most shoe shops have soft carpeting on the floor, so it’s a good idea to take a short walk on a harder surface before making a purchase. If the soles and heels make unpleasant clanking noises when you walk, you are likely to be wearing a low-quality pair. And platform or wedge shoes shouldn’t sound like there are voids inside the sole.
Examine the material of the sole and heel carefully.
Usually the sole of a really good quality pair is made of leather or good rubber. These shoes are comfortable to wear, and in addition, they almost don’t slip. At the same time, if the base of the sole is uneven, then these shoes will be uncomfortable.
In addition, it’s worth examining the material from which the heels are made. If the manufacturer used plastic or didn’t cover the heel with leather or fabric, then you are looking at a cheap product that is far from being perfect.
Rub the shoes with a cloth.
Sometimes manufacturers use poor quality leather dyes, which can leave marks on the skin or clothes. Therefore, before buying, you should carefully rub the shoes inside and outside, first with a dry cloth and then with a damp cloth. If there are no marks on the fabric, the shoes are okay.
And here’s a list of fashionable shoes that are not as cool as they look.
Why don’t airplanes fly in a straight line to save fuel?
Have you ever looked at a flight path on a map and wondered why airplanes take curved routes instead of flying in a straight line? Wouldn’t flying in a direct line be more fuel-efficient and faster? At first glance, it seems logical that a shorter distance would result in less fuel consumption, but in reality, aviation is far more complex.
Several factors determine flight paths, including the Earth’s shape, jet streams, weather conditions, and air traffic regulations. Let’s break down why airplanes rarely fly in a straight line and how their curved paths actually make flights more efficient.
The Earth’s Shape and the Great Circle Route
One of the biggest reasons airplanes don’t fly in a straight line is the Earth’s curvature. While we often view flight maps as flat, the Earth is a sphere, and the shortest path between two points is actually an arc called the Great Circle Route.
If you take a globe and use a string to connect two distant locations, you’ll notice that the shortest route often curves rather than follows a straight path. This is why flights from New York to Tokyo pass over the Arctic region rather than flying directly west across the Pacific Ocean.
Using the Great Circle Route helps planes save both time and fuel, even though it appears curved on a flat map.
Jet Streams and Weather Conditions Impact Flight Paths
Another key factor affecting airplane routes is jet streams—high-altitude wind currents that move at speeds of up to 200 mph (320 km/h). Pilots strategically plan routes to take advantage of these strong winds when possible.

Flying with jet streams allows an airplane to get an extra push, helping it move faster while burning less fuel. Flying against a jet stream can slow down the plane significantly, increasing fuel consumption. Pilots often adjust routes to avoid strong headwinds, even if it means flying a longer distance.
Additionally, storms, turbulence, and severe weather conditions also play a role in determining flight paths. Airplanes may adjust mid-flight to bypass dangerous weather zones, thunderstorms, or areas with extreme turbulence.
Air Traffic Control and Flight Regulations
Air traffic isn’t a free-for-all where planes can just fly wherever they want. There are strict regulations set by aviation authorities and air traffic control (ATC) that dictate flight routes.
Some of these rules include restricted airspace, where certain areas, such as military zones, national security locations, and political zones, prohibit commercial flights from entering. Predefined flight corridors exist to avoid mid-air collisions, ensuring flights follow established air traffic lanes. Major airports handle hundreds of flights daily, so ATC ensures safe and efficient arrivals and departures.
Due to these regulations, airplanes cannot always take the most direct path and must follow designated routes instead.
Avoiding Air Turbulence for Passenger Comfort
Turbulence can make a flight uncomfortable, and pilots actively adjust routes to minimize rough air conditions. There are different types of turbulence, including thermal turbulence caused by warm air rising from the ground. Flying at higher altitudes helps avoid this.
Mechanical turbulence happens near mountains and rough terrains where wind patterns shift unpredictably. Clear-Air Turbulence (CAT) is sudden, strong air currents in high altitudes that are difficult to predict.
To ensure a smoother ride for passengers, pilots may deviate from the shortest path to avoid these turbulent areas.
Why Do Airplanes Sometimes Ascend Before Landing?
If you’ve ever been on a flight where the plane suddenly climbs just before landing, you might have felt a bit concerned. This maneuver is known as a go-around and is actually a common and safe aviation practice.
Some reasons why pilots perform a go-around include runway clearance issues. If another plane hasn’t cleared the runway in time, pilots must abort the landing and circle back. Poor weather conditions, such as poor visibility, strong crosswinds, or sudden gusts, can make a landing unsafe. If a plane is too fast, too high, or not properly aligned with the runway, the pilot will ascend and try again for a safer landing.
Go-arounds are standard procedures in aviation and ensure passenger safety above all else.
The World’s Longest Non-Stop Flight
While most flights follow curved paths, some routes push the limits of non-stop travel. The longest direct commercial flight in the world is from Singapore to Newark, New Jersey, USA.
This flight covers a distance of 10,400 miles (16,700 km) and takes approximately 18 hours and 45 minutes. It follows a carefully optimized path to balance fuel efficiency, wind conditions, and passenger comfort.

What Happens If a Plane Suddenly Loses Cabin Pressure?
A sudden drop in cabin pressure is often portrayed as a dramatic event in movies, but in reality, pilots are well-trained to handle it calmly.
When this happens, oxygen masks automatically deploy, and passengers should put them on immediately and breathe normally. The plane will descend to a safe altitude where oxygen levels are sufficient for breathing. The flight crew will assess the situation and communicate with passengers.
Losing cabin pressure doesn’t mean the plane will crash—pilots follow strict safety protocols to handle such incidents efficiently.
Final Thoughts: Why Curved Flight Paths Are More Efficient
While it may seem counterintuitive, airplanes take curved routes instead of straight lines to optimize flight efficiency, fuel usage, and passenger safety. Factors such as the Earth’s shape, jet streams, air traffic control, and weather conditions all play a crucial role in determining flight paths.
So next time you’re on a plane and see the route map displaying a curved flight path, remember there’s a lot of science and planning behind it to ensure you reach your destination as safely and efficiently as possible.
