The original Teva Mush is a great for people who need extra support, especially for the arch, for just casual wear flip flops.  Since I have been buying the Teva Mush, I can go longer between purchases of my very expensive shoes that I wear out and about.  The Teva II doesn't work for me, only the Teva original but Teva II might work for someone with a longer, narrower foot.

I wasted a lot of money on shoes before finding Teva Mush. Now I don't buy anything else for around the house or dashing to the store. They're great!
