When families ask us which BILLY shoe to choose for an AFO, two names come up again and again: Goat and Limitless. Both are tagged AFO-friendly on our site, both come with adjustable laces and removable insoles, and both are available for kids and adults. So how do you choose? This guide compares them side by side using only what the product pages say, so you can see where they overlap and where they differ.
A quick note before we start: this is a comparison of features, not a medical recommendation. The right shoe for a brace depends on the brace, the foot and the person, so your orthotist or therapist's advice always comes first.

BILLY Goat: short wrap zipper, removable insoles, designed with orthotists
The kids' Goat collection is described as created in collaboration with certified orthotists for use with braces, orthotics and prosthetics. The Black BILLY Goat is the classic example: a short wrap zipper for easy on-and-off, removable insoles for adjustable depth, and an AFO-friendly tag.
What stands out in the product copy:
- A custom-developed last that adds width and volume in the toe box, vamp, quarter and heel.
- Removable insoles and a dense foam wedge insert for stability and depth adjustability.
- A triple-layer knit lining described as durable and tear-resistant.
- On kids' styles, a lateral heel flare and a slight forefoot rocker designed to assist gait propulsion.
The men's page for the Charcoal BILLY Goat adds that the short wrap zipper offers "convenient donning and doffing" and calls it one of the brand's most AFO-friendly solutions.
BILLY Limitless: full wrap zipper + laces, sensory-friendly lining, extra depth
Limitless is described on the product pages as designed in partnership with Children's Specialized Hospital (kids) and the Center for Discovery, Innovation and Development to give a sensory-friendly solution with additional depth adjustability, keeping BILLY's easy-on, easy-off design. The Lilac Watercolor Limitless and the Men's Black Limitless share these features:
- A full wrap zipper with adjustable laces.
- A sensory-friendly lining with a stitch-and-turn technique that creates a nearly seamless tongue and zipper guard, designed to minimise pressure from fluctuating foot swelling.
- Two additional spacer insoles for extra depth adjustability.
- A contoured heel cup and a sole engineered to cradle the heel.
- An extra-wide loop pull for people with limited dexterity.

Which fits which situation
Neither shoe is "better" in every case. These pointers may help you start the conversation with your clinician:
- Toddlers: Goat is offered from EU 20, while kids' Limitless starts at EU 28.
- Medium width: kids' Goat is offered in W and XW only. Kids' Limitless includes Medium.
- Sensitivity to seams or pressure: Limitless is the one built around a nearly seamless lining.
- Limited hand strength: the extra-wide loop pull on Limitless may help with the zipper.
- Heavy daily wear: Goat pages highlight a durable lining, and men's Goat pages mention increased toe durability.
- Depth for a brace: both use removable insoles and extra inserts, so you can adjust depth on either.
Width deserves a second look. Customer reviews on the Limitless page mention that widths can feel different between styles, so if you have owned another BILLY shoe, tell us which one and in which width.
