Hello folks, I hope everyone is having a great weekend! I have a pair of Goliath boots that are around a year old. I did a lot of walking/hiking in them and the heel part of their insoles is worn just below my heel (see picture) I've tried putting insole inserts and they get chewed up. Walking with the boots as they are is very uncomfortable and begets blisters. Can anyone suggest something to fix the problem or stop it from happening in the future? The rest of the boots are fine (testament to good quality!) and I am kind of hesitant to throw them away. Thanks for any advice!
