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 Technical Characteristics Brand: ZeroSole by Kaydiar Medical Model: ZeroSole Reliever Materials: silicone cells, memory foam mid-layer, poly-suede (moleskin) top cover Forefoot thickness: approx. 5.5mm Heel height (external): approx. 20mm Customisation: removable hexagonal cells Fitting: trim-to-size guides for UK, EU and US shoe sizes Footwear: conventional enclosed shoes, trainers and boots Usage life: 6 to 8 months of daily wear Supplied as: one pair per box Typical Applications in Prosthetics & Orthotics Plantar corns and callus Metatarsalgia and forefoot pain Plantar heel pain and plantar fasciitis Pressure-induced foot pain from worn or ill-fitting footwear Chairside interim offloading before custom foot orthoses are fitted Trialling offloading positions to inform custom insole prescriptions Long-term daily management and prevention of recurring lesions Typical Users Podiatry and chiropody clinics Orthotic and pedorthic clinics Foot health practitioners and diabetic foot teams (under clinical guidance) Hospital outpatient and community foot care services Pharmacies and retailers offering over-the-counter foot care What's in the Kit 1 pair of ZeroSole Reliever insoles Adhesive pressure-point markers for transferring the lesion position Instructions for use Sizes Small-Medium: UK 4-7 Medium-Large: UK 8-11 How to Fit Trim to size using the integrated guide Apply the marker to the pain point on the foot Step onto the insole to transfer the mark to the cells beneath Remove the marked cells by hand from the underside Insert into the shoe and wear People with diabetic peripheral neuropathy or peripheral vascular disease should use ZeroSole under the guidance of a podiatrist or other healthcare professional. The ZeroSole Reliever gives clinicians a fast, evidence-led way to offload painful plantar lesions at the chair, in everyday shoes, and to bridge patients to custom orthoses with immediate relief.
