If your talking about the Axial pro - under leather boot , yep ive got them. Had them for going on 3 years. Dainesse leather have the velcro under the cuff to grab on to the boot.
When i first got them they did feel quite rigid around the ankles. They even made my arch ache a bit after a while. You can remedy this by ( with the boot off ) pull and push on the ankle support. It doesnt take much and they now they fit like a glove. Also some isopropyl alchahol 50% in water in a spray bottle - put them on and give the outside a squirt and wear them around . Bend the toes over, basically give them a good work out. The 50% mix didnt do anything to the black colour on mine.
