They look good. Check it out. They are discounted. Check it out. The trendy seller says that they help the muscles of the pulp. Check it twice. Before you take the money out of your wallet, make sure that the sneakers, especially the training ones, do more than wrap the leg.

Shoes play a huge role in protecting your pelvis and hips, says Lori Thomsen, a physical therapist in Lincoln, Nebraska. Thomsen says that muscles, ligaments and tendons can become overworked if they don't have the proper support. This makes you more vulnerable to injury during a weight lifting session or run and also less competitive if you play sports. So don't listen to what the salesman says, stop and do this 3-point inspection. If the sneakers do not pass these tests, leave them in the store.

Pull the heel outward

When you push off the back of the heel, it should be firm and move very little. This immobility reduces movement that can damage ligaments and tendons.

Twist the sneaker

If it bends in the center, it indicates that there is poor arch support. Arch support maximizes the propulsive power of the hips and flexibility in the front of the toes responds to the natural movement of the toes.

Press the button

The base of the shoe should be strong, especially along the outer contour. The solid sole prevents you from tiring your ankles and feet too much and risking injury.
