Stainless Steel Fillis Irons supplied with black rubber treads. Fillis Irons are heavier than standard Irons, and very useful for Dressage and Jumping, as they help to give the rider more balance. 

For safety the iron should be wide enough to allow about 1/2" (1 - 1.5cm) on either side of the riders foot to avoid the foot getting caught in the stirrup in the event of a fall.
