If you are looking for a fairly light weight (in comparison to a boot) shoe, that can take a beating - this shoe will do it. I would say that they run true to size - i wear a size 8 in just about every other shoe brand, and these fit about the same- however, i would say that if you have a wider foot, this may not be the right shoe for you. I thought there might be a lengthy break in period with these shoes, since they have a very stiff sole, but i changed out the footbed to some gel insoles, and they are heaven. Able to cradle your feet in an array of conditions, from craggy rough, rocky, scree, to shallow bogs of weeds and swamp. I wore these out in BFE for some field work, and they were looking pretty wrecked - just hosed 'em off, and they were good as new. Never had that feeling of soppy feet - GO Gortex!!! And when i got stuck in a mini mud bog, they hung on tight (can't say that about any old shoe).
