Bought these recently as an upgrade over my original pads. I've moved from dek to ice, and found that I need a pair of shinpads that don't slip down my leg as much.
These are amazing for that. There are two straps, the standard velcro at the bottom of the calf, and a second one that goes ABOVE the calf muscle and holds the pad tight. Along with the wrap-around style of the hard shell, these stay in place right where you need them.
Two notes: There's a dumb design flaw in the strap, one of the pieces of velcro is removable. After I sized the pad on my leg, I had her sew it on the strap and it works as it should.
Also, I've noticed very small nicks in the edges plastic shell which I didn't expect to see so fast. I doubt they'll get larger, but it could be a factor.
Great value at normal price, amazing on clearance.
