Tonight i played with my vapors for the first time, didn't practise with them before that. They gave me the biggest blisters at the heel area. The second half it got so bad i couldnt walk, but still continued to play. I decided to wear them in warm hot water for 30 minutes, then walked around with them for 5 minutes. now they are drying, i gotta see what they are like now. Has anyone ever done this, did it work? also what are some other ways to prevent blisters, thanks.
