The only &#34;training&#34; you can do in these is sitting. They have memory foam inside that overheats the foot without offering any support, coated in a slippery silky material that doesn't help, the sole offers no support, flexibility and oh - don't lean back, that is the only soft part of the shoe and you'll find yourself falling. Wasted money.<br />(had RYKA before and loved them so this is about this shoe, not the brand)
