I've seen 2 or 3 pair of Adidas socks pop up on eBay over the last season and heard a few people saying the socks had velcro and that they were a different material than Reebok/CCM versions. I was able to pick up a couple pair of kevlar backed Adidas socks today and compared them to the Reebok/CCM ones I own. Since I hadn't seen another post comparing socks I figured I'd share.
They're the exact same.
The mesh on the upper part of the thigh is the only difference with Adidas mesh having slightly larger holes. None of the socks I picked up have velcro tabs or patches. The only thing that stood out as surprising is how much the Adidas tag wrinkles in the wash compared to Reebok/CCM.
new tag vs washed tag
Adidas thigh mesh vs Reebok/CCM
