This boot is the new BEST boot for English riding!  Normally when the ankle flexes during riding, the zipper will not allow the ankle to bend comfortably.  With the Essence, the zipper is at the corner and does not interfere with flexion.  The fun Kerrits tread is the right thickness for stirrup grip without too much bite.  All other boots are plain leather and only good for dry weather, but the Essence is waterproof!  Available in most sizes
