I love my Vapor Glove 2s, but they're wearing out. I was excited to get the latest model but when they arrived I discovered THERE IS NO HEEL LOOP! I love the heel loop because it allows me to put this shoe on easily while standing on the other foot (I've even managed it one-handed). I really wanted a new pair of these shoes but I'm returning them to get Vapor Glove 2s instead because the heel loop is a deal-breaker for me. (Though honestly, even though I love the gray/raspberry color scheme, I don't like the styling of the 3s as much either.)
