EquiFit Hind Boot Size Guide

Measuring your horse's hind ankle circumference is the most accurate way to size EquiFit hind boots. If your horse is between sizes, the ankle circumference measurement takes priority over height.

Size	Horse Type	Height (hands)	Ankle Circumference
Small	Large Pony	14.0–14.3	10.5"–11.25"
Medium	Small Horse	15.0–15.3	11.25"–12"
Large	Standard	16.0–16.3	12"–13"
Extra Large	Oversize	17+	13"–14"
XX-Large	Oversize+	17+	14"–15"

How to measure the ankle
Wrap a soft measuring tape around the narrowest part of the fetlock (ankle) joint, just above the point where the leg meets the hoof. Keep the tape snug but not tight, and level all the way around. Measure both hind legs and use the larger reading.

Between sizes? Choose by ankle circumference first — a boot that fits the ankle protects the joint correctly. Height is a guide only.

Sizing notes: Measurements shown are EquiFit's published hind-boot ranges. This chart covers hind boots and hind-boot replacement liners. Pony-size boots (e.g. MultiTeq, Pony Medal) run smaller than Small. On EquiFit's own chart the XX-Large row is labelled “Extra Extra Large.”

EquiFit X-Foam™ Replacement Liners are designed to refresh compatible hind boots without replacing the full boot. Made for Essential The Original hind boots, they help maintain the fit, feel, and protective support of the original boot system.

This is a compatibility-driven product. Before ordering, confirm your boot model, hind orientation, and size so the replacement liner matches the boot you are refreshing.

Fit, compatibility & care

Compatibility: Fits EquiFit Essential The Original hind boots. Don’t interchange front and hind liners.
