I had bought this legwarmer for my 10 year old son to prevent fall-related injuries in basketball. Orthopedic Bandages / Orthotic from Sanitätshaus are oversized for this purpose clearly: Too thick, too hard, too expensive. Similar products in the brand McDavid did not come for my son for design reasons in question. This legwarmer itself is generally of good quality, safe protection and supporting action is limited, but the application is indeed prophylactically for a healthy knee joint itself thought. Thus, they certainly served its purpose. ... And from the appearance clearly the coolest legwarmer the market. Only helps nix, if you need children's sizes and gets men's sizes. The smallest available size S slips on the legs of my son and will not be safe for use in the next 2-3 years. OK, the cuff is not classified as children size - but also not unique as an adult size. What's more, in contrast to the same type Armstulpe here only a single cuff is purchased, please be careful. And for the requested price is certainly no bargain. So for diminutive gentlemen certainly one worth considering investment, for children rather not.
