I bought this in 2016 and like many said the velcro didi it hold well. I went through three pairs last year before giving up. Vikram did however make a new model where THE VELCRO HOLD PHENOMENALLY! If you read bad reviews, it is from the previous year which was the debut. The heel cup does did a little if you wear without socks, so I ordered a sheepskin innersole for mine and took care of it immediately!
