La Sportiva NitroGym

The first climbing shoe made from a totally breathable and washable fabric, designed especially for indoor use.

The ideal choice for newcomers to the sport.  Also suitable for gym rental thanks to the three-layer washable WashTex fabric which keeps the shoe perfectly clean and hygienic at all times.  The perforated inner microfibre layer gives structure and flexibility to the shoe.  The super breathable inner fabric which is in contact with the skin allows sweat to be swiftly eliminated during long wear at the gym.

Every detail has been designed to enhance the overall comfort of the boot, allowing several hours of wear even with sticky feet.  The snug fit is enhanced by the construction of the central band linked to the lacing system, allowing the foot to be embraced completely and harmoniously.  The FAST LACING SYSTEM in Velcro allows perfect regulation of inner foot volumes.  The rental service is further improved with a visual aid which indicates when the shoe needs to be resoled, along with external numeration on the shoe.
