MedicalSoles Platinum Unisex

The Platinum RX+ is the brand's maximum-support insole on Amazon, built around a semi-rigid arch support, metatarsal pad, and deep heel cup, with an extra heel cushion of what the listing calls "super-HD cushioning." Amazon reviewers describe it as supportive yet comfortable — one compared it favorably to custom orthotics they'd worn for years — and it comes sized to fit with no trimming. One honest note: no insert alone resolves recurring heel pain — if it keeps coming back, get it properly evaluated.
