The Ultimate Roundup of Performance Accessories

The right accessories can change how your shoes feel—and how your body moves. This roundup cuts through the clutter to spotlight smart upgrades that actually work: carbon-assisted propulsion, alignment-driven support, maternity-ready cushioning, high-heel fixes, and everyday comfort that holds up from training to travel. Whether you’re chasing PRs, logging long shifts, or dressing up, these picks help you dial in fit, reduce fatigue, and keep your stride locked—no hype, just results.

Superfeet

One of the most established aftermarket insole brands. Known for its “signature shape,” deep heel cup, and arch-specific models aimed at comfort, alignment, and relief from common foot issues.

Carbitex × Blumaka 

Performance insoles that pair Blumaka’s high-grip platforms with Carbitex carbon elements for propulsion and forefoot support; designed to help with energy return and reduce over-extension at the big toe. Blumaka also offers an insole aimed at helping prevent hammertoe by supporting proper toe alignment and limiting over-flexion.

Heali Tape 

Kinesiology tape infused with menthol and magnesium for a cooling feel and muscle relaxation. Comes in rolls and pre-cut strips and is made to stay on several days.

FORM Insoles 

Heat-moldable (or wear-moldable) full-length insoles for comfort and pain relief. You can oven-mold for a custom fit or break them in over time. They also offer a dedicated maternity insole designed to support changing arches and added load during pregnancy.

Protalus 

Insoles centered on alignment with very deep heel cups and proprietary geometry to help guide foot motion. Popular with work boots and everyday shoes; lines like T-100 and M-100 highlight different use cases. They also make a high-heel insole tailored for pumps and dress heels to improve alignment and forefoot comfort without crowding the toe box.

S1 Tru Comfort Socks 

Left/right-specific cushioned crew socks focused on a snug, breathable, no-slip fit, designed to play nicely with ankle support systems and all-day wear.
