Columbia Karasi

Fantastic shoe at this price point. After first trying them I bought six pairs, and have already worn out two pair. Most of my running mixes trails, asphalt, and concrete. The Karasi is comfortable with all three surfaces, although I wouldn't recommend it for straight concrete or asphalt.

I think the reason this shoe is not more popular is the colors, they are just a little "off". Of the six pair I bought there are three different color schemes, none of which I find attractive. But if you want a really functional shoe or running or knocking around you can't beat them at the price.
