Vapor Glove shoes have been extremely popular since their introduction. Now in its sixth iteration, this model features the advanced Boa lacing system instead of traditional lacesfamiliar to many from other sports shoes. The Boa system allows for precise and even adjustments, and as a bonus, it eliminates loose laces hanging around, keeping them contained within the systempreventing them from getting caught in bike gears or other obstacles. The Vapor Glove concept remains the same as when it was first introduced: by removing a stiff midsole and cushioning, the shoes still protect the soles of your feet but allow your muscles to work in a completely different way. Over time, as your feet adapt, they strengthen, and your stride becomes more natural. The Vapor Glove is Merrells purest barefoot shoe, designed for those who prefer minimal cushioning and flexibility. - Standard fit - Breathable, membrane-free upper fabric - Lining and insole made from recycled materials - Cleansp
