We believe that this is the first ever complete breakaway stirrup designed which can be used across all disciplines.

  • Revolutionary Award winning Australian design available in adult and child sizes in a variety of colours.
  • The Bostock Safety Stirrup has been tested for over 7 years before coming to market. Permitted for use in British Eventing. 
  • Designed so that when there is a shift in the riders weight and the rider passes through a point of no return the bottom part of the stirrup comes away from the top, thus greatly reducing the possibility of being dragged.  The outer part stays attached to the stirrup leather and the saddle and in the inner part releases with the foot.  (A normal fall should not mean that it breaks apart).
  • Simple system to reassemble - click the two parts back together making sure the arrows line up .
  • Wide foot plate enabling a good grip and foot balance.
  • Available with Black, Blue, Red and White colour detail.
