Had to return these, they were just a little too tight. If you don't have large calves, then they are not too bad for the price.whatever happened to tube socks? got tired of socks built for "sizes 6-11" and having the heel stick out the back of my shoes... took forever to find these but glad i did: perfect, right up to the knee, not too long, not too short... great colorsThese socks have the quality expected. The size is cut small, so my size 11 feet are tight in the socks. After the first time they were washed the fit did improve. My thought is that if you have a size 11 or larger foot, the socks will not be a good fit.When I saw these tube socks I was so excited. It took me way back. I just had to get them. The problem with these was there was little to no elastic or stretch so they are tight on my calves. I have purchased other tube socks and calf socks I wear with my boots before that are more comfortable at the mid and upper calf. The foot feels great. I like the cushioning in the foot, i just do not like the feel on the calves. A little more elasticity here would be beneficial.I'm 5'10" and wear a size 11 shoe and these socks truly are over-the-calf, easily. With a little stretching they could probably go over my knee. They haven't gone through the wash yet but fresh from the package they are definitely the longest/tallest tube socks I have ever owned. And they stay up. The only thing that is a little strange compared to other socks is the seam is directly at the end of the sock, across the tip of your toes, instead of over the "knuckle" like most socks. Not a comfort issue, just different. I will definitely buy these again if they don't shrivel up in the wash, lol. Very comfortable, soft and "cushiony". And did I mention, they stay up!not much stretchBased on product ad, I purchased these Sox for a person with a disability. Definitely do not waste your money.Good pair of socks but had to cut the ends off so they wouldn't restrict the blood flow above my calves. Wish they'd have a little more elasticity in them.
