If you are looking for a well made, zero drop shoe, I could not recommend SOM footwear enough. I've got several months (and many miles) on my Nutrail Cross Sports and have been nothing but impressed by them so far. You can tell that they put some serious thought into every detail of the shoe. Glad to have found a US made shoe that looks good, preforms well, and is pretty competitively priced.
