Gaerne SG-12 Boots , Size: 11, Distinct Name: Black, Gender: Mens/Unisex, Primary Color: Black XF45-5352 Dual Stage Pivot System: This revolutionary new system is patented and exclusive to Gaerne and is certainly going to be a hit. The first pivot is attached to the Razorback. This provides a rigid component that offers a strong lateral support while a glide-plate keeps the upper in a firm and upright position. The second pivot is fixed on a sliding glide that allows the riders foot to feel natural while on the peg in a shifting or breaking situation - however it will bottom out and absorb shock in the case of over-jumping a jump or in the case of unwanted compression Grip Guard: On the inner side of the boot is the rubber Grip Guard.
