The grip on the back is very helpful. I am used to these socks cutting into the part of my foot by my toes, so I thought if I ordered a tad bigger (I am an 8.5 and ordered the 9+) then it would stop it from happening. I was wrong, definitely order true to size! These do fit big on me so they have a ton of extra space under my heel and when I put my shoes on, the entire sock bunches up on the back of my shoe and it's uncomfortable. My own mistake, but lesson learned to order true to size on these! They are a far more comfortable fit and cut than the ones I am used to, so do not cut into your foot anywhere. I will just give these to a friend with bigger feet and order my regular size.
I wear size 10 shoes. These sock are perfect. Thickness is just right for my casual sneakers. Length is perfect, no cramped toes. They are not meant for running or hiking, Awesome for a whole day of walking, shopping looking good.
I have so much trouble with my feet hurting. I have come to believe there is no such thing as a comfortable pair of shoes. These socks cushion my feet so that they don’t hurt so much. In fact, I now wear them instead of going barefooted at home and they really help. I made a second order because I wear them all the time. Actually I wear them when I go to bed because they are so soft an cushiony and ease the discomfort in my feet . They are delivered quickly and well packaged.
The socks are thick, soft, nice material BUT the heel is too generous. I ordered the large & have size 11 feet. I washed in HOT water & put in high heat dryer TWICE but the heel is just too bulky. It just bunches up on top of the back of whatever shoe I wear. Such a pain to have to adjust & tuck-in and wiggle. I have the large end of the foot size (9.5-11) so I thought excess fabric wouldn't be an issue, but I was wrong. There is a comparison pic of another type I tried (Vero) and they don't have excess heel fabric. I would not recommend this brand but the "V" brand is very good.
The problem with no show socks is they usually don't stay up. I constantly find myself adjusting and taking my shoe off to pull up my sock. Well, with these new socks this is a worry from my past. These are so comfy, the thickness adds a nice cushion to them, and they stay put perfectly. I can wear these with any kind of shoe and not have to worry about adjusting my sock every two minutes.
I wear a shoe size 6 1/2 ladies and ordered a Small. I found these socks to be very comfortable but they were too large so when I wear them with tennis shoes, I have to tuck them in which is not that comfortable. I do wear them alone to Pilates and they do not slip off.
