They had the right idea with incorporating the Velcro in the sock so that that it attaches securely to the all in one cup/sock garter. I use the Shock Doctor version and it made perfect sense to get these socks. Too bad RBK only put Velcro only for the top the thigh and not the back of the thigh. It would be nice to have the sock secured fastened around the back of your thigh. Sure... the Velcro on the Shock Doctor somewhat grabs the material on the back of the thigh area, but it's not the same as the top. Now I will have to spend another $10-$15 to have some Velcro stitched on in order to make a better fit.
These socks seem to run a little large in my opinion. I wear a good sized shin guard and they are loose fitting. Perhaps after a wash and maybe a littler dryer time they will shrink up a little.
