PRO GRIP stirrup straps, maximum GRIP for training and competition FREEJUMP's single strap stirrup straps and extra-wide design offer unsurpassed riding comfort and the guarantee that the FREEJUMP stirrup straps will not twist. The upper part allows an even more precise adjustment of the length than in conventional stirrup straps thanks to the use of "biothane" material on the back of the upper part of the stirrup straps; The biothane reinforces the upper part of the stirrup straps so that there are more holes at the same short distance (30 holes instead of 20 as with conventional stirrup straps). The new PRO GRIP range: Internal grip of the leather for a better grip on the saddle ; As a result, the stirrups are more stable; No need for grip between the boots (or chaps) and the leather/saddle pair, limiting the secondary effects of boot glue, and allowing the legs to remain free in their movements; Grip mounted on a Velcro for easy replacement ; Leather also comes with a leather strap (mounted on Velcro) without grip ; Special rubber material with a surface for maximum desired grip;
