Perfect entry-level climbing shoe for all day comfort at the gym or crag. With an upper fabric that consists entirely of Black Diamond's Engineered Knit Technology, the Momentum provides stretch where you need it, support where it matters and all-around exceptional breathability. Black Diamond have also added a microfiber liner to the front of the shoe to minimize stretch and maximize comfort. The Momentum’s durable rubber is unique in that it’s moulded (inspired by the way Black Diamond forge their carabiners), versus cut from one sheet of rubber. This is Black Diamond's engineered solution to optimize our shoe’s rubber and rands for weight, consistency and comfort. Built for all-day comfort on moderate routes, boulders or gym sessions, the Momentum features a soft flex midsole for sensitivity and is the perfect entry level climbing shoe. Features include: Knitted fabric upper with zonal stretch and structure. Double velcro straps. Twin pull-on loops. Flat lasted for all-day comfort. Hemp footbed. 4.3mm sticky rubber sole. Vegan friendly.
