I am all about Altra shoes and these are their only waterproof shoes.  Overall, I think they are pretty good, but they still have some issues that hopefully will be fixed in the 4.0 version coming out in August 2018.

Good for rain and cold weather...too hot for warm weather

Pros
- Typical Altra fit, same size as my escalantes, torrins.  The newer 3.5's require sizing up 1/2 size, while these did not for me
- Good fit, ample toe box, even a larger than normal
- Decent traction

Cons
- Waterproofing works pretty well, but after 8 of 10 miles in pouring rain they started to leak a little, still not bad
- A little warm for summer running, but in the rain they work well.  Better for colder weather I imagine
- Traction could be a bit better, no Vibram rubber
- Waterproofing makes toe crease hard until you break these in

Overall a good shoe from Altra, not their best, but maybe the 4.0's will fix this
