One size fits most adults and kids shoes.
Self-adhesive, peel off backing to secure in place. The ‘sticky’ test. Some surfaces are not suitable for any sticky back gel inserts. To test yours, place some ordinary sticky tape where the insert is to go and wear the shoe for a day. If it falls off immediately, it might be that nothing will stay in place.
Soft silicone gel material prevents heels from scratching and blisters.
Excellent for fitting shoes with a generous fit.
