विवरण
The ZeroSole Reliever is a customisable pressure-relief insole designed by UK podiatrists for the targeted offloading of corns, callus and other pressure-related plantar foot conditions. Its patented hexagonal silicone cell grid lets the clinician or user remove individual cells by hand directly beneath a painful area, creating a personalised offloading zone in minutes.
Unlike gel or foam insoles that give uniform cushioning, ZeroSole combines full-length cushioning with focused pressure relief exactly where it is needed. It does this in a slim, low-profile insole that fits conventional enclosed footwear such as trainers, work shoes and boots, without the bulk of traditional modular systems or the need for post-operative shoes.
The insole is ready to use straight from the box, making it ideal for chairside fitting: patients can leave the appointment with immediate pressure relief, including as an interim solution while custom foot orthoses are being designed and manufactured.
Key Features
-
Targeted customisation: remove any hexagonal cell by hand to create bespoke offloading under one or more pain points
-
Evidence-led: laboratory pressure mapping (UWTSD) showed an average 28% reduction in pressure at targeted areas compared with standard footwear; a 6-week clinical evaluation (Cardiff Metropolitan University) showed statistically significant pain reduction and decreases in plantar lesion size
-
Chairside fitting: customised in minutes without grinding equipment, adhesives or additional workshop time
-
Bridge to custom orthoses: provides immediate offloading before custom insole fitting, and helps identify the offloading pattern a patient responds to
-
Low profile: approximately 5.5mm at the forefoot for everyday enclosed footwear
-
Durable: medical-grade silicone retains its shape for 6 to 8 months of daily use, outlasting compressible felt and foam padding
-
Arch support and heel cup: help redistribute load across the foot
-
Developed by podiatrists: created by UK podiatrists David Barton and Heather Smart, and used across the NHS and UK retail pharmacy
