Don't order white....
My previous jumper strap was black and wider than these straps. It also had only one pull over strap with velcro. Always worked fine. These are for my wife who says her knees get tired... I tried one to see if they were effective. In general i would say YES. BUT like another comment stated... I liked the pad in the back and the adjustable straps with velcro in the front. The narrow pad fits nicely behind my knee and adjusting straps in the front is very easy! So far my wife prefers the pad in the front? Please don't order white, try grey instead if you want something other than black. During my test run I wore a white one mowing the lawn. Not a smart decision. Also, if you have tree trunks for legs you may fine these a bit tight.
