I've been looking for a pair of very lightweight, flexible shoes/booties for P90X routine for certain exercises that I had been doing in socks or barefoot - particularly the 'Stretch X' routines.
I'm trying to avoid slipping on the carpeting where I work out for those routines.

Tony Horton actually wears a pair during the stretch routines, and he briefly mentions that fact at the beginning of the routine (he calls them 'Easy Soft' shoes). I could not find them anywhere on Web.
Nor do they appear to be sold on the Beachbody forum.

Does anyone know the exact name and where I could find them?
Or something of near-identical / similar construction?

I've noticed a number of Yoga/Pilates shoes/slippers for women, but that doesn't help if you're male.

A lot of serious fitness trainers get custom made shoes. Just like everything else they wear. But here's some shoes I found.

This one is not exactly a yoga shoe but it's what I wear and it's about the most confortable and lightest shoe I have ever worn. Just don't step in water with it.

Thanks, MrPhil. A few interesting options to check out.
I'd still love to know what Tony Horton was wearing.
