First pair leaked(I'm talking total bottom of sock soaking from the side). Montrail replaced for free (great customer service!). They stated it was a bad batch. Then, my replacement leaked as well (again from the side). Also owned the mid of these that again leaked from the sides. I'm not talking condensation build up, or water over or down into the collar of the shoe. I'm talking gaiters on with rain pants, walk through a 1.5" high puddle and your foot instantly feels cool with water. Frustrating! I've also had the sole start separating on two pairs of the shoes, but in all fairness, I've logged many miles in both. The tread on these shoes grips really well in crappie terrain and sheds mud surprisingly well afterwards. The fit on these shoes really is great for my feet for trail running. I've had friends as well who love the fit of these shoes but also have had leaking problems. I'm not impressed with outdry or the quality of the sole, but love the fit of these shoes.
