This is a great looking boot, and the design features provide the ultimate in lower leg protection. Sleek design contours the cannon bone and protects against impact and concussive injuries without bulk. Suspensory strap wraps under the fetlock to provide critical lift and support for suspensory ligaments. Boot base is cut higher in front to match the natural curve of the horse’s leg, allowing full flex and extension while reducing bell boot interference. ArenaSEAL boot design works in tandem with the suspensory strap, creating a seal that keeps arena dirt from accumulating up inside the boot. This is the only boot on the market with this feature. Extensive line of colors to complement any professional color palette.
