I typically use them to workout so I'll give them a smell test after a workout but wearing them multiple days in a row was something I had never considered, thanks!

Interesting, never heard of that, will check it out.

Good advice. I also think there's a local store I can send them in, but not sure how much of a hassle that will be. Like if I have to drive to a store twice, might be easier to just send them in.

Is "darning" a typo for "patching"?

I do a fair bit of athletics and normally the heel is the first to go, but the front part of the sock is close to done too. Very stretched and worn. I wouldn't want to patch that.

I did have to go up a size. I wear a size 12 shoe and I needed the 12.5-14 sock. My feet are also wide I think and the socks are a bit snug but still comfortable for me.

I think mine are similar, I could never wear Nike shoes as they were too narrow for my feet. I had to go up a size and they fit ok but I definitely see your point.

>If you wear out your socks with use over 5-10 years it is, IMO, a bit of an overreach to expect a free replacement.

But.. that's the appeal. Assuming the company still exists they have a pretty clear replacement policy as long as they're not missing or an animal doesn't destroy them. Sure, a shipping fee but I think local stores will send them in(from what I've read).

Run ~5 miles about 4x a week and play a bunch of tennis. Also, might just be an issue with the sock design. The heel would often stretch out and mostly break there.

I kept most in storage and would just take out a pack at a time when I was running low.
