I bought the Vapor Glove2s ab 6 months ago and I've put them through a lot of wear and tear. I've worn them for 13 hour shifts at work, trail running through mud puddles, foot launch training for HG. I've washed them countless times both by hand and in my washer and they've held up beautifully.  Not the slightest separation of sole, nor any degradation of any part of the shoe. They're wonderful. I bought this pair last week and they fit as much like gloves for my feet as the 2s do. Plus I get a lot of compliments on their looks, and working in a hospital means everyone is interested in good and stylish footwear. I'll never buy anything but Merrills again. They're brilliant.
