about 3 days ago, i noticed that there is a hole worn in my liner that leads straight to the very outside of it. it's right on the inside of BOTH of my ankles. i can't really tell how big it is since i can't really see, but i'd say about an inch across. i've been riding the liners for maybe 75-100 days including summer. they are not intuition liners, just regular liners on some 09 technica boots with the regular tongues. i haven't noticed any pain from them, yet.
anybody else had this happen to them? what causes/ prevents it? can these holes lead to foot injury somehow? do i need new liners?
+k to serious, helpful responses.
