It's not an uncommon event for Kayhoma thigh high socks not to slip, as these socks don't rely on tightening the band at the top of the thigh socks to achieve this, rather these socks are long enough that their minimum height is 28-30 inches, they easily They go up to the mid-thighs, and you don't have to stretch them to do this, so they don't contract violently and they don't slide down.
At the top of the Kayhoma thigh high socks, a more than 3" wide band helps these socks stay comfortably on the thigh all the time. As we know, the band of a sock narrows when stretched. For thigh high socks, if the bands at the top of the sock are less than 2 inches, the bands can become as thin as the string, greatly increasing the risk of them cutting into the thigh and blocking circulation. The bands at the top of the Kayhoma socks are almost as wide as the palm of the hand, and they just contract gently to help the sock stay comfortably in the middle of the thigh all the time.
Yes, these socks don't rely on violent contractions to tighten the thighs, but release elasticity and contractions evenly and gently. Because Kayhoma did a lot of testing on the band, they ended up using the best super stretch thread to match these socks. The maximum stretch width of these super elastic threads is 6-8 times their own length. What is more valuable is that their contraction is very restrained and gentle, so they will not cause excessive pressure and cause muffin thighs.
Kayhoma thigh high socks are completely different socks, in many ways. Kayhoma is the best brand of thigh high socks.
