The problem with gym insoles

Most workout shoes ship with insoles that are essentially decorative foam. They compress within weeks and do nothing for pronation, arch variance, or the uneven force distribution that accumulates over a long lifting session. Off-the-shelf orthotics are better, but they're sized to an average foot — and feet aren't average.

Fits Perfect makes a custom version built around your actual foot geometry, which is the core pitch here. We've seen custom orthotics run $400–$800 when prescribed through a podiatrist's office; at $249, these occupy a genuinely useful middle ground.

What makes these different for the gym specifically

The design choices are clearly sport-first rather than walking-shoe repurposed. The polypropylene shell is calibrated by weight — a meaningful detail that off-the-shelf insoles skip entirely. It provides structure without rigidity, flexing like a spring under load rather than cracking under repeated impact.

The heel cup is deliberately shallow, which sounds counterintuitive until you realize that deep heel cups common in dress-shoe orthotics create fit problems in snug athletic footwear. Here, rear-foot control is achieved without adding stack height that fights your shoe's collar.

The forefoot gets 1mm of Poron® foam — a medical-grade open-cell material with better energy return than standard EVA — specifically for impact diffusion during aerobics, plyometrics, and anything involving a hard floor. The perforated EVA top cover moves heat out; a small thing that matters during a 90-minute session. The suede-like bottom layer grips the shoe's insole bed so the orthotic doesn't migrate under multidirectional movement, which is a real failure mode with cheaper inserts during lateral exercises.

Fit in practice

Because these are custom-made, they need to be trimmed or fitted to your specific shoe — Fits Perfect provides guidance on this. The low-profile construction means they'll sit inside most training shoes without crowding the toebox, but if you're running in a highly cushioned maximalist shoe (Hoka, Brooks Glycerin), you may need to remove the stock insole entirely.

The 0.13 lb weight is barely perceptible.

The honest caveats

At $249 you're paying for customization, and the value of that depends entirely on whether you've identified a real biomechanical need. If your feet feel fine during training and you've never dealt with ankle instability, plantar fasciitis, or knee tracking issues, you're buying insurance you may not need. We'd also note that custom orthotics — including these — work best alongside a proper fitting process; used with a shoe that already fits poorly, they can shift problems rather than solve them.

The red colorway on the perforated EVA top is sport-appropriate but non-neutral — worth noting if you rotate across multiple shoe colors.

The bottom line

For athletes who've been told by a physio or their own experience that their feet need more structure, Fits Perfect's fitness orthotic is a well-engineered, purpose-built solution at a price that undercuts clinical alternatives. The material choices — Poron® forefoot, polypropylene shell, suede grip base — are legitimate, not marketing vocabulary.
