A high-performance indoor climbing specialist, the La Sportiva Theory is massively adaptable: both super soft and sensitive while being powerful on small edges at the same time. La Sportiva has used Vibram® XS Grip2 for maximum friction; there is no midsole to make the shoe softer and more adaptable. They have even differentiated thickness at the toes for better sensitivity. The Theory uses D-Tech™ construction to wrap the sole sideways around the sides of the shoe for great No-Edge feel on the sides but maintaining the edge on the front of the shoe for full power on small holds.
