Herm Sprenger Ultra Fit Extra Grip Spurs are made of high-quality stainless steel and guaranteed against breakage. The elegant design fits perfectly on the riding boot. The durable and long-lasting black rubber cover provides an even better fit and an attractive look. The cover also prevents the spur from slipping while protecting your boots from metal scrapes and rubs. Protection for your boot leather also comes from the Balkenhol fastening, an innovative design where the spur strap loops are not parallel. The spur straps fit much better, pressure and movement are eliminated as a result. The neck or shank of this spur is 25mm.
