WonderZorb Heel Cups

WonderZorb by Silipos is a line of silicone-based cushioning products built for one job that matters to anyone on their feet: absorbing the shock that travels up through the heel with every step. If you're dealing with heel pain, plantar fasciitis, or the sharp discomfort of a heel spur, these cups sit inside your shoe and take the impact your heel would otherwise absorb bare.

The WonderZorb WonderSpur Heel Cup is the centerpiece of the collection. Its medical-grade silicone is dense enough to support your weight but soft enough to cushion the strike point, and the design distributes pressure away from the tender central heel — the exact spot that flares with heel spurs and fasciitis. Because the silicone stays flexible, it molds to the shape of your heel over time rather than flattening out like foam inserts tend to.

Fit is the first question most buyers have, and it's straightforward here. The line comes in sizing tied to shoe size: the Medium WonderSpur (4501) suits smaller-to-average feet and ships as a clear/blue pair, while the Large WonderSpur (4502) covers men's shoe sizes 8 to 10 and women's 10 to 12. Both are sold by the pair, so you're treating both feet from the start. The open, cupped shape drops into most closed shoes, sneakers, and work boots without crowding your toes.

A common concern is durability and hygiene. Silicone wipes clean easily and can be reused day after day, unlike disposable gel pads, and it won't break down from sweat the way fabric-covered inserts can. Many users rotate a pair between two pairs of shoes to keep relief consistent throughout the day.

WonderZorb cups pair well with broader lower-limb care. If you're managing chronic foot discomfort, explore related options in our Foot Care selection and the wider Orthopedic Soft Goods category.
