A few positive things to note:
- Wide toe box for splay;
- Ample cushioning;
- Good ground feel;
- Breathable and flexible upper; and
- Durable shoe.
A few negatives to note:
- It can be a bit tricky to shoe on and off, particularly when wet;
- The flex grooves pick up stones when trail running; and
- It takes a few weeks/months to build-up the foot and leg strength for these shoes (even if you are a minimal runner)
My previous shoes was a New Balance MT1010, which seemed to lack cushion for the long runs. I wish Nike made a trail version of this shoe with a bit more cushioning and a thin rock plate.
