Best Arch Support for Plantar Fasciitis
📋 Testing methodology: Each product was worn for 42 days in standardized footwear (Asics Gel-Kayano 30 + Clarks London). Arch height measured before and after with digital calipers. All products purchased with our own money. Last tested: 2026-07-12. Full protocol →
The right arch support for plantar fasciitis must balance firmness (enough to offload the fascia) with comfort (enough that you'll actually wear it). We measured the arch height in millimetres before and after 6 weeks of use for each pick below.
