The brand new Arena children's stirrup collection is based on many years of research, development and success of our Acavallo stirrups Arena. The patented side opening arm is produced using an innovative injection molding technique. The outer articulated arm of the stirrup facilitates the release of the foot in case of emergency. The opening of the stress-actuated locking and unlocking mechanism is located one centimeter higher than the tread to prevent the foot from slipping sideways by mistake and sand and dirt from delaying the opening action of the arm. Extra-wide, high-strength, form-fitting tread for maximum riding comfort. Made of a high-tech combination of metal/polymer materials and certified high quality anodized aluminum. Developed and manufactured in Italie. Maximum weight: 80 kg Weight: 703g per pair Maximum arm opening: 90mm One size fits all Sold by pair Clean with a cloth. Store in a clean and dry place.
