Review: Merrell All Out Rush Trail Running Shoe

When I was offered to try out the Merrell All Out Rush Trail running shoe I was excited especially when I saw that Runners World voted it the Best Debut trail running shoe.”

This trail running shoe has a light and responsive ride, with a 6mm drop and 15mm of cushioning to bridge the gap between minimalist and traditional running shoes. On their site Merrell says:

A flexible underfoot wrap creates continuous contact with the arch for increased mobility. Ultra-resilient UniFly impact absorption gives you first takeoffs and soft landings. Get a grip with any terrain with the multi-directional M Select Grip Traction.  

To translate the marketing speak its supposed to have a really good grip, and be flexible with your foot to give you more mobility and cushion impact. The question is, does it do what it says on the tin?

The shoe does give you a more natural running gait. They are light (205g) and they shape well to my feet at least. I am impressed with the grips. I was getting across a river by jumping on the wet mosey stones and I didnt feel my foot would slip, and so got over quickly without having to worry. It also gripped well on wet grass.

The All Out Rush shoe is comfortable and does deal well with grass, mud, sand and stony surfaces. Although, while trail running in Snowdonia, on an old roman road, I could distinctly feel the sharp stones.

The only downside to Merrells All Out Rush shoe is that there is no waterproofing at all. It makes no claims for this and is not built to be this way. If you take a look at their promotional video, the woman advertising them is running in a very dry part of the US. However, my reality is running in the UK, where it rains a lot without warning. 

The verdict? Its a good trail running shoe with excellent grips and support. My only recommendation, Merrell, is can you please make your trail runners with some waterproofing for those of us who live in wetter and unpredictable climbs?
