Evolvs best selling shoe back with a facelift and tech update for even more crushing. Defy everything The Defy one of Evolvs best selling climbing shoes and a great all-rounder. It has gone through several technical upgrades making it an even greater choice for beginners all the way to advanced climbers.The most notable difference after the visual updates are an improved anatomical fit for greater out of the box fit and comfort. A new synthetic upper will keep the shoe from overly stretching and a nice padded and breathable tongue adds a functional and comfortable surface for the two velcro tabs to wrap around. Evolv have also built-in a new anti-microbial mesh material known as Agion to eliminate odour and bacteria build up. The Defy technical enough to smear along slabby terrain or grip an overhang, and comfortable enough for a day climbing indoors, or a multi-pitch epic.The Defy retains Evolvs VTR Variable Thickness Rand technology. VTR a new technology that makes the toe rand in differing thicknesses. Basically, high wear zones are thicker and more durable than other areas, this enhances the toe box structure and prevents toe bulge. It also means that there less waste during the manufacturing process so its better for the environmentOverall, a great shoe that will stay comfortable from the first time you put them on but still let you climb hard.
