they are nice but they have a problem with the sizing. The sleeve is tick and not very streachy. As a consequence, the sizing has to be spot on. The medium-sized pads were too large for me and they were sliding down, but the small-sized ones were too small in the calf area and the compression was uncomfortable for rising. Maybe with some wear, they would have become more comfortable. This is the first time this happens to me with knee pads. Normally, I fit very well in the small size of other brands including other models of Leatt. Advice...
