Tech Venice Sloped Evo are sloping stirrups (2.5 degrees) made of aluminium that help you to keep your heels down. The stirrups have a movable ring which is fitted with a spring. This allows the stirrup to open if necessary (for example in the event of a fall). It is important to make sure that the movable part of the stirrups opens and closes automatically before you use them. Tech Venice Sloped Evo is designed for showjumping/eventing. Maintenance and care: To extend the life of the tread, you should clean your boots before riding and wash the stirrups with water after each use. Weight: approx. 560 grams/stirrup. For shoe sizes 35.5 to 37.5.
