MaxArch — Firm Support That Won't Collapse
The Plantar Fasciitis Reset
"First arch support that didn't fold flat under a 95-kilo guy. You can feel it actually holding."
Left unchecked
If the arch support collapses under your weight, it isn't supporting anything. Soft foam feels great in the shop and pancakes within weeks — and your plantar fascia goes right back to overstretching.
That morning heel stab is an overstretched plantar fascia screaming.
If it compresses flat under load, the arch gets no real lift.
An unsupported arch changes your gait and loads knees, hips and back.
MaxArch is built firm on purpose — a high arch cradle that holds its shape so the support is still there on step 10,000.
How it works
Firm support feels different at first — here's how to settle in.
Replace your existing insole with MaxArch in a snug, closed shoe.
Wear 2–3 hours the first day so your arches adapt to real support.
Build up over a week to full-day wear — most people stop noticing them and just notice less pain.

Wear it for
Firm arch support offloads the plantar fascia where the morning stab lives.
How Curavi fixes this
The firm 3.5cm semi-rigid arch cradle holds shape under up to 150kg of body weight, providing the consistent lift the plantar fascia needs to relax and heal. Unlike soft foam insoles that flatten under load within hours, this maintains true structural arch height through full-day wear.

Questions, answered
Yes — and firmness is the point. Real arch support has to resist your full body weight transferring through the foot with every step, which is roughly 1.5x your bodyweight at peak load during walking. Soft foam insoles that feel plush in the shoe collapse under that load and end up supporting nothing.
The semi-rigid polymer cradle in MaxArch maintains true structural lift through the entire gait cycle, which is what actually offloads the plantar fascia. Ease in over 3–5 days — your feet will adapt quickly to the new support pattern.
They work best in snug, closed-toe shoes with removable existing insoles — trainers, work shoes, hiking boots, and lace-up casuals are ideal. Pull out whatever insole is in there and drop MaxArch in.
They won't fit comfortably in slip-on shoes, sandals, or very flat dress shoes because the rigid arch needs the shoe upper to hold the foot in place against the support. For those, look at the HeelSheath sleeve or MassageStep insoles instead.
Yes — the arch cradle is engineered from a specific grade of EVA-reinforced polymer that maintains its 3.5cm arch height under loads up to roughly 150 kg of bodyweight without deforming. We test each batch under static load before shipping.
If you're at the heavier end of that range and want to be sure, your first week of wear will tell you — if the arch still feels firm by day 7, the support is doing exactly what it should. If it's softened, contact us and we'll replace under warranty.
For ongoing pain relief, daily wear is the answer — once you've eased in over the first 3–5 days, switch to wearing them in your main daily shoes from morning to evening. Inconsistent wear doesn't deliver consistent results because the plantar fascia needs continuous offloading to actually heal.
Most users feel a meaningful difference in heel pain within 7–14 days of consistent daily use. If you only wear them on workdays and skip weekends, expect slower progress — but still real progress over 4–6 weeks.
Try them daily for 30 days. If they haven't reduced your foot pain by the end of the month, return them for a full refund — no questions. Plantar fasciitis is stubborn and not every case responds to arch support alone; we'd rather refund you than have you keep insoles that aren't doing the job.
Return shipping is on us within the US, and refunds process the same business day we receive them.
