The extender is an accessory for the Enduro model of Scoot Boots, and can be used to position the bulb strap higher on high heeled horses. Price is for a PAIR of bulb strap extenders.
IMPORTANT: Do not position the bulb strap so high that its top edge is poking into the pastern. There should be at least a finger's width between the top edge of the bulb strap and the bend in the back of the pastern. Unlike the heel strap on traditional Scoot boots, which must hook over top of the heel bulbs, on the Enduro model it is OK for the bulb strap to sit behind the heel bulbs.
