These are incredibly comfortable, and when I first got them I was *very* happy with them. They stay up pretty well too (tho not perfectly by any stretch of the imagination, but better than I expected) I wear them as my "house socks" sorta like how you might wear slippers for comfort in the early morning and late evening. They never leave the house.
Given how/where/when I wear them I expected them to last a good long while (about a year), however, about 2 months after buying them (this review, including image, being written/taken a little over 3 months after purchase) they started to wear away at the ball of the foot. In fairness, this is where all my socks wear through at, but usually it takes 3+ years for any type of wear (other than dirt and grass stains) to show up on the cheap (15-20 bucks off-brands for 4 to 6 pairs) crew or over-calf socks; which I treat much rougher (mowing lawns, running, sprinting, hiking, etc.)
To be fair I have multiple pairs (about 5 to 7) of "normal" socks and only 1 pair of these, but it really doesn't feel like it adds up to me.
I get that different materials are needed for thigh highs to work (what with the incredible need for stretch and "staying-up" power), but I'm still sorely disappointed.
I'll likely end up cutting them to the bridge (there doesn't seem to be wear on the heel) and hemming them so they don't unravel.
TLDR;
If they were cheap then I would not be surprised at all, but I specifically went out of my way to get something from a reputable brand that cost a decent amount cause I wanted to enjoy them for a good long while, especially given the price, purely indoor usage, and treatment. But instead they started showing signs of wear at the ball of the foot in about 2 months, with this review being made a bit after 3 months.
PS:
as a potential point for improvement in the future, maybe add a bit of a "binding" material to the feet? potentially a sorta coating, or extra weave, or using another material at that section (even as a second weave into the base layer)
Washed on cool (not straight cold) water, and lowest heat in drier (mine has no "unheated" option).
