Convenient. Bought for Kid's Bowl Free and worked great the first time I put them on. Saves you from putting your foot in a shoe that many other smelly feet have been in, which is nice. Not the most attractive things, but bowling shoes are rarely like this. They just look like regular black tennis shoes. :) The size corresponds. They have a large slide zone on the bottom if you are more of a pro bowler who slides. Recommended price.
