LeMieux Vector Balance Stirrup The LeMieux Vector Balance Stirrups are advanced safety stirrups designed for outstanding rider balance, shock absorption, and support. The ergonomic footplate is set at 5 degrees with a cross-track grip surface embedded with hardened steel pins for boot security. The integrated safety arm has a two-stage release system that ensures it opens in case of a fall but not during typical riding maneuvers. LeMieux Vector Balance Stirrups have aluminum construction that is lightweight yet strong and durable. Ergonomic footplate set at 5 degrees 45 degrees outward orientation Weight 419g each Aviation grade Aluminum Cushioning dynamic polymer layer One size Besides the balance and security offered by the Vector Balance Stirrups, riders will appreciate the superior cushioning and impact absorption. The footbed is mounted on a cushioning layer of dynamic polymer with a 70% compression rating. During jumping, vibration and impacts at the point of landing are absorbed by the polymer layer. This reduces the stress on muscles, tendons, knee and ankle joints. The twin balance arch system distributes weight evenly across the base of the stirrup frame. With a frame that is recessed and off-set, the rider has a more comfortable foot position and can quickly pick up a lost stirrup. Technically advanced LeMieux Vector Balance Stirrup gives riders the security, safety, and cushioning they want with contemporary LeMieux style.
