Soles

Mapped, not molded. SolesRX exists because orthotics were stuck between a guess at the drugstore and four hundred dollars at the clinic. We take the clinic’s inputs, read them from a phone scan, and print the remedy. Most insoles are molded from an average foot. Yours isn’t average. It has its own arch height, its own pressure map, its own way of striking the ground. SolesRX turns a short phone scan into custom, medical-grade insoles, built one pair at a time. HOW IT WORKS • Set up your profile and start a guided foot scan • Capture both feet in sub-millimeter detail with your iPhone • Review your fit and choose custom 3D-printed insoles • Shop ready-made options when you want something sooner • Track your order and manage your account in the app THE FIT IS IN THE DATA We measure before we make. Every build starts from a point cloud, not a mold, backed by a library of clinical scans and printers that build the correction one pair at a time. PROOF OVER PROMISES If we claim it, we can show it: the scan, the map, the print, and an industry-leading guarantee behind every pair. BUILT TO MOVE Orthotics belong in running shoes and work boots, not in a drawer. We build for the miles. Podiatry • 3D Printing • Biomechanics Three minutes with your phone. The rest is ours.

Verdict
The clearest difference is update cadence: Sensor Bio at weekly against Soles's every 6 weeks. Soles's advantage is iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
