After trying 3 brands I decided to go back to Riedells and get custom skates. I love them except the padding is so stiff around the heel that my heels literally go numb after 10-15 mins in them. My question is, how many times is it safe to heat mold them? And will the padding break down enough to ever be comfortable? I’ve dealt with Achilles tendinitis for 2 years so we intentionally built it up but I think it’s too much.
