GUIDELINES FOR PURCHASING THE CORRECT SHORTS

These easy steps will help you find the right shorts for you that will become your faithful training and competition partner:

Put on the trousers and put the suspenders and the bottom of the leg in place so that there are no creases, the feeling once the shorts are worn must be of slight adherence.
Keep the shorts on for a few minutes by bending your legs, and getting into bike position, then try to pinch the fabric in the thigh area and if once the fabric is released the Lycra returns to its position then you have tried the suitable size to you.
If, on the other hand, you feel an unpleasant sensation of rubbing or constriction, or if the seams or the straps are too tight, try the higher size.
Alé pads do not require the use of creams because they are soft and comfortable and are designed to be worn next to the skin without any intermediate layer.

Many times the problems encountered during the use of the garments are not attributable to the shorts themselves but to the wrong choice of size or model or to errors in washing the garments (see above), in fact:

These easy steps will help you find the right shorts for you that will become your faithful training and competition partner:

The suspenders, the elastics, the bottom of the leg tend to roll up when wearing the garment but can easily return to their place with a few small gestures.
Lycra must provide a massage to the muscles and a slight compression effect, and only if it remains very close to the body can it perform its function properly.
