I have them and I like them alot. My riding shoes don't have very deep treads on the soles and they do move on the floorboards from the vibration of the engine. I'm thinking I'll get some of that gripper tape they put on stairs, etc. to fix the problem. Every place I find that tape it's in a 10 ft roll. I need about 6 inches! My garage is already full of left over stuff like that.

pps:
Next I'm looking for those bath tub stick-ons in black. Maybe I can buy a small amount and cut to fit.
Maybe, also, I should finally get some new riding shoes! Do you think?
