WHY ARE SOME TUBE SOCKS EASY TO CUT OFF BLOOD CIRCULATION？
The first is that some tube socks is litter small, and do not have great elasticity. They are only suitable for very thin calf. These socks can not meet the big calf, just only barely cover the top of the calf, but because the socks are not elastic enough, just only 30 minutes later, they began to cut off the calf, leaving a deep mark. The second case is that the socks are elastic, but the elastic band at the top is only half inch. After being stretched, the elastic band starts to become like a very thin thread tied to your calf, easy to cut off the calf circulation. In fact, these situations can be avoided completely. The designer should considered those calf which have good muscles. The elasticity of the sock needs to be more than 2 times than the ordinary socks, because the calf may be much larger than the foot. In addition, the elastic area on the top of socks should be designed to be wider.It should be as wide as a belt to protect the blood circulation, at least one inch or more, not as narrow as a shoelace.
