We present to you a new line of products modeled by SparkyCanDo. These are 3d printed inserts which enable you to use magnets to create your own removable soling!
Stop lugging around a spare pair of footpaws for use outdoors, and switch to a single footpaw with a removeable indoor and outdoor sole!

These come in two flavors: With magnets, and use your own magnets. One order provides enough holders for both feet, and two soles per foot.

Please see this link for a picture tutorial on how to install these in the soling. You can buy these here.
