I am 6' 3" tall, 205 lbs. These should give good protection and seem like good quality, but did not want to stay in place and straps were not comfortable. Only 2 straps going behind calf. Stayed in place in sitting position on bike, but if I got up or moved around, pads would shift on my leg. Concerned that they would shift in a crash as well. Inside of strap is scratchy side of velcro and uncomfortable on my leg. Had to return.
