Note on the trails I have used these shoes on: the trails are mostly maintained (most areas are clear of major debris like fallen trees or large rocks, though a few stretches are a bit more wild). The ground quality ranges from loose dirt to small rocks to muddy, and there is one minor water crossing. There are a few elevation changes, though the majority of the trail ground is on flat elevation. There is only one water crossing I typically run across, and it is dry half the time.

As mentioned in the product description, these are minimalist shoes. This means that rather than a bunch of cushioning as found in regular shoes, all you really have between your foot and the ground is the rubber outsole (and in this case a minimal, removable insole - just note that if you want to remove the insole there is more space and you might want to try a slightly smaller size). You can definitely feel the ground through these shoes, while still retaining protection from sharp rocks and other hazards. This protection also extends to the front; the toe cap is reinforced (nothing solid like plastic or metal, some sort of pliable material is used) and the outsole curves up a bit to protect the lower portion of the sides. The lugs are also great. I traverse a few hills with loose packed sand on a couple routes, and the lugs  really dig in and keep me from sliding anywhere even when it gets a bit steep. I find that they also handle mud quite well. Despite all this the lugs aren't really noticeable while running. The material on the top and sides are very thin allowing it to breath rather well, though it seems tough enough not to tear when twigs or whatever trail debris scratch across it. I think the lace/tongue structure is also nice; rather than an independent tongue and lace structure the shoe is built kind of like a loafer. Thus you can slip the shoe on, and tighten the laces to adjust the fit. The laces are nothing special, though they are a bit longer than necessary - if using a reef knot with a bow and moderate tightening, the ends of the bow nearly reach the ground to the sides. The shoes are relatively light, weighing about 9.5 oz (.60 lb).

I have not used these shoes across any significant stretch of water. I have found that they dry fairly quickly when they are exposed to water. I am a bit suspicious the outsole might slip a bit on wet rocks, so I would recommend carefully testing before running across rocky streams with them.

Overall I think these shoes are great for trail running and I definitely recommend them.
