Firstly, this is a completely honest review of mine as this is my fav store period. Really like these and also the rugby/programming socks, they are a bit different fabric I feel like, bit thinner and sturdier also stretch more, even tho the product description says it's the same blend (percentage).
These socks are amazing, thick, grip your legs well and get especially comfy after a day or two of wear. (get softer). They are really nice for couple of weeks but then they will stretch out and that is probably the main issue what makes them less comfy overtime. Obviously they pile since it's acrylic you have to be gentle with them but it's inevitable either way. That is fine because I don't think that's why they get less comfy it's the stretch.
I have wore these easily for 2 years almost multiple pairs and the problem is that they stretch out after a month+ and you simply can't get them back as they used to be, as result they get less snug as they no longer grip your leg I think that is the main problem. Washing shrinks them little back but not as they were before and they stretch out back even quicker. (Tried highter temperatures even to boil water and gently squish them).
The Rugby/Programming socks suffer from this too and as they are slightly thinner you notice this even more than with the Longer Pride ones. That is the sad truth : (
(I am not overstretching them btw, I am somewhat fit so my legs are not chunky)
Amazing socks for first few weeks after that not as much, for their price I just can't recommend them pretty much one use socks. (Don't get me wrong obviously you can still wear them until they tear or smth but they just don't feel premium anymore, not worth 20+ bucks)
I don't know if Sockdreams can figure something out, a way to get them last (as they were the day you bought them) for longer than a mere month... probably making the fabric more rough but they would lose their comfort.
edit: Normally I wash them in a cold water either by hand or using delicate mode on the washing machine. Based on the support's suggestion tried to shrink them once using hot water, didn't work. After a month or two they are simply never as snug as they were, more loose and stretched.
I have some cotton ones too, definitely more durable however less warm, less soft still good tho. Recommend
