ENGO blister prevention patches are patented low-friction patches manufactured with pressure sensitive adhesive. The patented technology reduces blister causing friction by more than 50%. Unlike other blister prevention and relief patches, ENGO patches are applied to the inside of footwear, to the surfaces of insoles, or to socks - NOT TO THE SKIN. This means the patches provide long-lasting protection from blisters and are pain-free to apply and remove. ENGO patches are thin, sweat-proof, water resistant and latex-free.
