    Merrell's All Out Crush performs very well and cleans up easily.

  • 90 / 100 | Obstacle Racing Media | | Level 1 expert

    Great OCR shoe.

  • 80 / 100 | Running Competitor | | Level 5 expert

    It features a lightweight TPU-film-reinforced upper with drainage holes for water displacement, plus an aggressive multi-direction lugged outsole made from a super grippy rubber compound.

  • 89 / 100 | Running Warehouse | | Level 4 expert

    Add the 6mm offset to the flexible sole and soft foam, and you’ve got a very well-balanced, smooth-riding, do-almost-anything, light weight trail shoe.

  • 88 / 100 | Active Gear Review | | Level 4 expert

    The shoe runs well for the most part, but I find the fit in the toe box to be a too narrow for a medium width fit giving the shoe an awkward fit compared to other trail running shoes on the market.

    The All Out Crush by Merrell looks to be a nice lightweight mountain shoe for hikers and runner who want to move fast through demanding terrain.

  • The upper of the Merrel All Out Crush has a bulky airy mesh but is very cool because there is no barrier that will stop the air from cooling the foot. On wet and muddy grounds, the upper is wet but will tend to dry up quickly as the water is pushed out easily from the shoe with a draining system of two draining holes on both sides.
  • The upper is enhanced with a TPU cage pattern, a new innovation for shoes, which makes the shoe more durable and very easy to clean after tracking down the mud. Synthetic overlays are also added to the construction of the upper, and it comes with soft gusseted tongue and flat laces that hold the foot tightly and securely.
  • Merrel uses the Uni Fly midsole and plate for just a minimal amount of cushioning and for stability. There are two drainage holes on each side of the shoe as well for quick drying purposes.
  • The outsole has the Merrel Select Grip rubber sole with 5mm lugs. This design is for optimal efficiency on any obstacles, especially for the tough mudder competition.

The All Out Crush offers a new sock like fit in its upper. The toe box area has a snug fit on its nice shape and volume. The mid-foot is also made more secure with the upper construction combining the open air mesh and synthetic overlays, and the heel area is snug without slippage for a more confident ride on trails. This shoe is available in standard running shoe width and length.


The outsole of the All Out Crush features the M-Select Grip outsole, a Merrel exclusive rubber outsole. It has lugs in 5mm designed in a great pattern for better traction and grip and for versatility. The rubber compound is soft and flexible, with flex cutouts in the forefoot area, while the lugs are solid. This outsole material is also used in the Merrell All Out Crush 2.


The midsole of this Merrell running shoe is made from integrated EVA foot bed for its cushioning and the TrailProtect pad on the sole for added protection.


The upper of this shoe is made from the mesh materials with TPU synthetic overlays. A protective toe cap is also placed for added protection. These materials made the shoe cool and breathable, more durable, and easy to wash and dry up.
