I have two pairs of these and one for casual wear, and one for running. As has been said, they don't have arch support. That's why I'm using them for running as a supplement to barefoot running and runs in my Vibrams. It takes some getting used to, but they're perfect for minimalist running if you're into that sort of thing.

I buy these Tigers because of the way they look. They are beyond cool, with their ultra low-profile design. They're sexy shoes with a definite European flair to them (though they are Japanese by design). You see these frequently around Paris on the feet of the younger generation. Even though I'm in my 40's they still look cool. You just can't find a cooler-looking, old-school style sneaker. I get compliments all the time. This, I may add, is my second pair, with 2 more on deck. Even my 14 year old son fell in love with them since nobody at his school wears them. So they have a certain "hard-to-find" cool factor that makes them more doable to many. Having said all that, they are not the most supportive shoe out there. In fact, they really are just for looks. You could run in them because they're so light, but they have zero arch support so it would be somewhat like running barefoot. The sole is flat and thin, of course. Still, they're like a feather and they look great. If you want serious running or walking shoes, these aren't them. But if you want some cool shoes, look no further.

I love this shoe. I wear (and bought) a Women's 12N. I bought it as a comfy, casual shoe that wouldn't look so athletic. The material is a soft, thick felt, and goes great with jeans or casual pants. I have been wearing it nonstop since it arrived! I will consider adding an insole for some arch support and don't anticipate it affecting the fit.

I love my new kicks! These are just what I was looking for in a casual, yet hip looking sneaker. Easy to dress up, great with jeans... Others have complained about the tabs that stick out of the back, but it's easy enough to just tuck them in and they go unnoticed. Not sure how athletes ran with these in the Olympics, with such a thin sole, but they are super comfy for walking around town. Love 'em.

I have about 8 pairs of these in various colors. They go great with many styles of jeans and they are not as flat or hard as other classic track shoes or similar styles.
