The only reason I got rid of my first pair was because the sole had completely worn down smooth and became very slippery and dangerous. Short but a pretty good horror game. I am unsure on the sizing, but I had an old pair of her slippers and put them sole to sole and they are the same length. Game was too short. I have an S20 with great sound when being used through speakerphone. I was pleased to find out that the company stands behind their product 100%. Remember to orient the rubber base so that it will provide a flat mounting surface for the rack on the sloped roof of the car, one side is taller and there is a top and bottom. Went to Monoprice chat line for help. All in all a solid choice in a rather dry market. The nine year old asked for this style and we obliged.
