Designed to offer climbers maximum comfort, the THEORY liner from LA SPORTIVA will accompany you on every climb. Designed for gym use, this men's model offers sensitivity and feel.

This indoor shoe has been designed to make it easier for athletes to move around indoor climbing holds, thanks in particular to the D-Tech TM construction, which spreads the surface of the arch of the foot thanks to the absence of lateral edges, for better support on technical holds.

Thanks to its double tongue, you'll be able to put it on quickly before tackling the routes you've always dreamed of. Vibram® XS-Grip2 technology improves grip. The patented P3 system promises to maintain the shape of the liner over time. A model so light you'll forget you're wearing it!
