Customer Reviews

Comments: I agree with Simon, the shoefitter deal is off. However, the last is a little bit too curved and too narrow (for me.) They feel (fit wise, not ride wise) like the first version of the New Balance Minimus did. That fact out of the way, Merrell built a really solid winter running shoe-- note that I didn't say trail shoe. The upper is kind of a ripstop nylon material that shelters your foot and feels great in sloppy conditions (I wore it today in 3'' of snow and slop and my feet came out warm and dry.) That same upper though isn't super breathable, which leads me to believe it would be a poor summer trail shoe. The ride is also super firm, which I wasn't expecting with a shoe that has such a big midsole. I kind of wish they lowered it in order to give the shoe more stability. No worries though, most trail shoes are on the firmer side. The outsole is a deal breaker. Its just okay. Its grippy enough for snow, but thats about it. I wouldn't take this on a technical trail or out when there's a lot of loose dirt/ sand/ snow; its just not aggressive enough. It's also stiff as a board; some flex grooves in there wouldn't hurt any. I hope Merrell keeps at it though, the allout rush is very underrated and could be a really solid shoe
