The Ass Kicker does precisely that! Made from a genuine Vibram boot sole on one side and 1/4" thick leather on the other side. The leather side gives a nice traditional smack you would expect. Flip it over to the boot side and it can give one hell of a bite!
Leather portion available in a range of colours. Custom orders welcome. If you can imagine it, I can probably make it!
*Tread pattern may vary from paddle to paddle. Bear-Things is not responsible for lasting boot prints left on rumps, or the insane amounts of fun which can be had doing so!
