Add-On Soles and Inserts

Make your soft sole shoes ready for more. Add a Big Runner rubber sole for outdoor walking (sizes 3 and up), or a removable natural wool insert for extra warmth and cushion. Choose the same size as your shoe.

Good to know
Shoes with added Big Runner soles are final sale, so please check your size first. See our size chart or reach out and we'll help you find the perfect fit.
