Overview
Lifting the arch and locking the ankle at the same time is what the BioSkin TriLok does: a FootLok strap supports the arch while a figure eight wrap stabilizes the ankle. One bilateral design fits either foot and can be strapped against rolling in or out.
Supporting arch and ankle together, which a compression sleeve does not do, is the reason to buy for plantar fasciitis and sprain recovery. The strap sequence takes a few wears to learn.
Who it's for
Athletes returning from ankle sprains and people with arch pain who still wear trainers or cleats fit here. Those who want something they can pull on in seconds should choose a sleeve.
Pros and cons
- Supports arch and ankle together
- Fits either foot
- Adjustable for inward or outward roll
- Low profile for most shoes
- Strap routine takes practice
- Shoe size chart needed to order
Performance notes
The arch strap lifts the foot from below while the figure eight wrap limits ankle roll, so both are controlled by one brace. Strap tension sets how firmly it holds, and the wrap direction decides whether it resists inward or outward rolling.

Frequently asked questions
Will the BioSkin TriLok fit in cleats?
Yes. It is low-profile enough for trainers, flats, boots and cleats, and fits in most court shoes.
How do I size the BioSkin TriLok?
By shoe size, not circumference. At the bottom of a size range with a narrow foot, size down; at the top of a range or with a wide foot, size up.
Is the BioSkin TriLok hard to put on?
There are four straps and a specific wrap path. The listing says most people have it down by the second or third wear.
