I don't know if anyone's gonna have info on this:
I have a lot of wool socks. Fox River and Darn Tough hold up forever. However, my Smartwool PHD socks are durable, and my Smartwool Non-PHD socks all have holes.
I really, really want durable Merino toe socks for running and wearing my Vibrams. My Smartwool PhD Lightweight Run socks are showing great durability, but I'm getting between-toe blisters on long runs and I can't use them with vibrams. Anyone know if the Smartwool PhD toe socks are durable? I have the Non-PHD ones and there's holes on all kinds of rub spots. I don't want to drop more money on something that lasts 3 months.
Let me know,
Max
