I've retired from barefoot ultra-running, and now spend a couple hours a day in the gym on the elliptical, doing mainly jumping exercises.  I'm never comfortable in standard padded shoes, and the really bare-footed shoes like Vibram's Five Finger line is a little odd-looking (I have a few pairs and never use them).  I picked up the white version of this shoe the first time for around $90 and thought it's a little overpriced for its actual quality when examined in person.  But here on Amazon, I found extra pairs for under $50.  A bargain!  My first pair, going on a year of daily gym use, is still holding strong, so my extra pairs are in storage.

This shoe comes with an inner built-in sock, which is attached with 2 plastic buttons to the shoe - one in the back of the shoe (A big polygon button) and another at the bottom of the tongue.  The sock is a bit tight, so I took it out.  If I don't use socks, my sweaty feet feel kind of funky in the rubbery shoe.  So I use cheap black no-show socks and they're fine.  The big, big deal about these shoes:

First, so easy to clean!  Use a stiff brush under running water, and you can scrub in an out of the shoe.  Let it airdry and you're set!

Second, the big hole in the back of the shoe - when you don't use the built-in sock - you can pull your gym pants through this hole so you don't step on it.  I find that all gym pants are too long, and so sticking them into the back of the shoe, and pulling them out through the back hole solves trhe issue!

Just a great shoe when you don't like padding.  With 4 of these pairs, my first one lasting into its second year, possibly 3 - I should be set for the decade.
