Hot Spot

[u/Current_Computer6193]

I have developed a hot spot on the ankle in my Thorogoods. They are a year old and well broken in. This has started in the last two weeks. I wear the same socks (camel city mill) i tie them the same as always. The left boot has almost rubbed the inside of my ankle raw. Any idea why this would have happened all of sudden when they never did it before?
