I run in New Balance MT101s (can you still get these?) and have a few pairs still in the box as I like them so much. Grip doesn't look too hot but they are great for trail and dry(ish) fell. Grip isn't too much of a problem unless you are racing or its really really muddy. The biggest problem for me with minimalist shoes is that the uppers aren't really upto constant scuffing from rocks and heather.
