Winter "fashion items" also have hidden dangers, doctors urgently remind...

Review expert: Wang Xuejiang, professor at Capital Medical University

After the winter solstice, people are about to enter the "freezing mode". In order to prevent "frozen hands and feet", people have turned their attention to thick-soled, furry "snow boots". Although this "fashion item" is comfortable, it also has health risks and safety hazards. Doctors urgently remind: Don't wear shoes with a sole thickness exceeding one number!

Thick-soled snow boots pose health risks

Some snow boots are not suitable for children. The fur of these shoes is usually long, and after wearing for a period of time, the fur will be "collapsed", the internal space will increase, and the insole of the shoe may become slippery. Children are prone to slipping and falling when walking.

The soles of some snow boots are thick and hard, and lack curvature, so they cannot cushion the impact of the ground on the lower limbs. Children need to lift their heels harder when walking, and their foot muscles remain tense, affecting their arch and bone development.

Rehabilitation doctors remind you: Thick-soled shoes extend the resistance arm, place higher demands on the ankle muscles and ligaments, and weaken the perception of the ground, affecting walking stability.

In addition, thick-soled snow boots will change the mechanical structure of the entire lower limbs when walking, affect the movement rhythm of the ankles, knees and hips when walking, and increase the risk of injury.

For friends who drive, wearing snow boots may also cause some troubles.

Because snow boots can easily get stuck between the accelerator and the clutch, and the control of the accelerator and brakes is not sensitive enough, it can easily cause rear-end collisions and brake failure.

Therefore, it is recommended to friends who like to wear thick-soled shoes and snow boots: the thickness of the sole should not exceed 3.5 cm!

How to choose snow boots?

If the temperature where you live is really "freezing your feet", or if you want to travel to the Northeast or other places, you must wear some thick shoes. How should you choose them?

1. Check the product label of the snow boots.

The content of the label includes necessary information such as trademark, product name, shoe size, material, company name, and implementation standards.

2. It is recommended to choose leather and fur snow boots.

There is a visual difference between animal leather and artificial leather that have not been modified with special techniques. The former has a soft color while the latter is often bright and dazzling.

Remove the fur inside the upper and look at the fur joint inside. If the fur is dense at the joint, the fur grows on the leather board, and each pore is evenly distributed, then the fur is integrated. If there are obvious weaving warp and weft lines, it means that artificial fur or wool is woven on the base fabric.

The fur of the integrated fur feels dense and elastic; while the artificial fur feels fine, the fur is sparse and less elastic.

3. Pay attention to the material and pattern design of the sole.

Good soles are delicate and smooth, without visible bubbles and shrinkage, and feel flexible and elastic. Poor soles have poor elasticity, rough workmanship, and feel stiff.

In addition to the material, the pattern and depth of the sole will also affect the anti-slip performance. The sole without pattern is easy to slip. The depth of the sole pattern is moderate. If it is too shallow, it is easy to slip, and if it is too deep, the sole is easy to break.

How to deal with slippery roads in winter?

Always be alert: The roads are slippery on snowy days, so you should always be alert. Especially those roads that seem to have no snow but are actually covered with a thin layer of ice are often the easiest to ignore, but are also the most likely to cause slips.

Learn to walk like a penguin: When walking, keep your feet shoulder-width apart, lean forward slightly, and walk slowly with your center of gravity down. Don't put your hands in your pockets to help you maintain balance and provide emergency support in case you fall.

Wear warm clothes and non-slip shoes: When traveling on snowy days, you should wear gloves and warm clothes; when the road is slippery, remember to change into non-slip shoes with deep grooves. High heels have a small contact area with the ground, and hard flat shoes have a low friction coefficient, so they are not good choices.

Slow down your walking speed: always pay attention to road conditions, find a safe path, avoid slippery places such as ice and snow, and walk in small steps instead of running.

Avoid walking in the dark: Insufficient light on snowy days increases the possibility of slipping, so try to avoid traveling at night and carry a flashlight if necessary.
