Just got a pair a couple of weeks ago. I chose them because I am definitely a shuffler... the hard toe on the non-slide shoe works exactly as advertised.
I has been watching them on-line for a while now, hoping the price would come down. When I saw one site only had a few sizes I went ahead and got them, thinking they may soon be discontinued. Got them from Buddies, no problems - free, quick shipping.
I'm very happy with them. Ordered my normal size and at first they felt a little tight, but were fine by the 3rd wearing. Slide is good, I'm using the slickest heel which is a little slicker than I'm used to, but the next heel is grabby - need to use it in practice to take the edge off.
I really should get new shoes more often - they always seem to help my game - force me to think about my footwork (and slow down!).
