These come in a set of 36 pieces. 14 shoe-side and 28 sole-side. Includes pre-installed neodymium magnets. Installation is no extra cost.
Why is the price for magnet installation so high? We've switched to using large, high-grade neodymium magnets. It's worth the extra money to have magnets powerful enough to prevent your removable soles coming detached while walking or dancing.
These are magnet holders for swappable indoor and outdoor soling for us in 1cm thick eva foam. The top hat goes into the shoe-side foam and the toothed piece goes into the soling. View photos for instructions.
