    A lot of good protection, great traction, and the fit was really nice--a lot of room in the toe box. So, for me, this shoe is a big win.

    The shoes felt great on the run. I had felt I had a good amount of cushioning and that I never lacked for grip when I needed it.

    The Merrell AllOut Rush did not work out well for me as a running shoe – it felt too firm underfoot and I felt like the weight-balance was more boot-like than running shoe-like.

    The shoe is a bit on the firm side. Not as firm as the All Out Fuse felt on the roads, but still pretty firm.

    It offers a happy medium between proprioceptive feel for the trail and cushioning and protection from rocks, roots and other trail debris from the durable rubber outsole.

    Flat-footed ride with little feel for the trail and too much rigidity.

    In my opinion, the most impressive thing is the grip. Downhill, even on a wet, slick surface, was no problem.

    I did a single knot today, just as a trial… and sure enough, within two-and-a-half miles, both of the shoes were loosening up; one of them came fully untied. So, I went and double-knotted them… and they're fine the rest of the way. The rest of it: very comfortable shoes.

    Combining a fabric upper shoe with a synthetic rubber sole, the shoe is lightweight and molded to fit around your foot’s curves with ease.

    The All Out Rush is a great new addition to Merrell's line for a runner who wants to take on the trails with a little bit more underfoot.

    If you look at the outsole, you're gonna see some aggressive lug patterns. Each individual lug is siped, so as you move it can flex and clean, and still grip and pull. The Merrell sticky rubber compound should perform in wet or dry conditions.
  • Brett Shop Zappos
    It has an upper crafted from breathable mesh ad TPU, with reflective surfaces for visibility in low-light situations.
  • John Running Warehouse
    The All Out Rush uses our Merrell Omni-Fit lacing system to provide a precise, glove-like fit and our breathable mesh lining is treated with M-Select Fresh for odor control.
  • April Shop Zappos
    The midsole is lightweight, made with Unifly, to help absorb impact and give you fantastic energy return.
  • John Running Warehouse
    The midsole/outsole has a 6 mm drop and our patented Unifly technology, which disperses impact, stabilizes for a solid take-off, and really hugs the arch.
  • Shaun Bohnsack RunningShoes.com
    This product is definitely more geared towards the trail, so you'll see this product actually has a 5 mm lug on the bottom of it. Very aggressive lug. This product also has a little more cushioning.

Updates to All Out Rush

Merrell takes the All Out line to another level by not just adding something to a barefoot experience. In the All Out Rush, Merrell features a shoe that can suitably function as a hiking boot because of its large and tank-like outsole. Although the outsole is quite firm and very thick, it does weigh much lighter than it looks.

The continuous outsole also gives the shoe a high-level of durability and stability with flexibility as the trade-off. Because the outsole is one solid mass of rubber, runners can expect a more stable, durable platform at the cost of limited flex or less natural movement.

All Out Rush size and fit

Merrell’s trademark snug fit in the heel and midfoot with a wide toe box is clearly present in the All Out Rush. The delightful locked in feel of the heel and midfoot that widens to a spacious toe box usually benefits most runners. Medium is the offered width of this shoe. Sizing is fairly regular with options from 6 to 14 for the men’s and 5 to 11 for the women’s.

Outsole

The whole chunk of the outsole is dominated by circular lugs with a few opposite facing rubber configurations in the forefoot and the heel for enhanced downhill or uphill movements. Merrell uses its own M Select Grip rubber compound all throughout the outsole for optimal traction on different outdoor surfaces.

Midsole

The whole midsole is blanketed by the Merrell-unique UniFly. This foam is made of premium-grade EVA together with Merrell’s own technologies to give it excellent rebound features and cushioning. It also allows decent ground feedback despite the adequate support and protection. Underfoot protection is increased by firm plates that are located in the heel and the forefoot.

Upper

The AirMesh is a proven material in providing excellent breathability. With numerous overlays from the midfoot to the heel, the All Out Rush offers serious midfoot and heel lockdown feel. The unique Omni-Fit lacing system gives runners a glove-like and dialed in fit. Lastly, reflective details in the upper make running in low-light conditions safe and quite a treat.
