I just got a hold of a barely used set of Reebok XLT Pros and the knee cradle was removed. I have used a velcro knee strap for years and it just works for me but, alas, it is no more on this new set. I'm not planning on modding these pads a great deal but do want to add a leather strap to the knee block for now but can't figure out how to install it. The hole for the strap in the knee block is only the width of the strap so not sure if it has to be folded and forced into the hole or is there some other trick. Any ideas how to add a knee cradle after-the-fact?
