    One of the best things about them [that] I found is the grip.

    For neutral runners, this shoe is great for mixed terrain running for pretty much as far as you can take it.

    The cushioning and midsole have a good balance so there is a touch of softness that feels forgiving while the shoe is firm enough and structured to also give stability.

    We found the trail feel to be just right on reasonably rough ground, striking a balance between a connectedness with the lumps and bumps of natural terrain and a suitable amount of protection against the repetitive impact of running.

    I was quite impressed with this shoe. The thing that strikes me the most is that there’s nothing really gimmicky about it – it’s not MAX cushion, or a barefoot shoe, or [insert favorite shoe ‘feature’ here], it just shows up ready to work.

    The amount of grip provided also impressed me; 5mm lugs in sets facing differing directions do well to limit any slipping and sliding – the middle lugs even looking like they'd be at home on a rugby boot. And it isn't a heavy shoe either, each one weighing around 283g.

    My knees are fine, thanks to the shock absorption in the soles, which help to spread any impact, and although your feet do get wet, they don’t feel waterlogged, as the mesh sides allow for some egress. That rubber bumper at the front has saved me from a few stubbed toes on tree roots.

    The sole is quite thickly padded and also very flexible which means you get a bendy shoe with a good bit of protection from treading on small stones – the bane of a minimalist trail shoe wearer’s life.

    I went out for a 5-mile run. The first part of the run was fine. I went over some stones and I did feel some pain.

Updates to All Out Charge

Merrell comes up with a trail shoe that puts a premium on connection and protection in one go in the All Out Charge. Getting the perfect blend of protection and connection is something that most shoes struggle with. However, with Merrell’s move to add cushioning to the All Out line results to a plusher feel with better protection without taking away the very important ground feedback, especially on the trail in the Charge.

The All Out Charge is a mid-weight trail shoe with a slightly firm sole for a fast feel and an improved platform for powerful takeoffs. It is also a rarity as a trail shoe as it has several minimalist features, but is designed with a little stability in mind to take the runner from fast runs to daily high-mileage training.

Merrell creates a more versatile, very rugged, and protective All Out version than many of the past models. It is a shoe that finds a lot of sweet spots between traditional runners and those looking for a more minimal footwear. Runners who are looking for a no-fuss and do-it-all trail shoe should be delighted with Merrell’s introduction.

The HyperWrap 360-degree Fit offers the stretch and support in all the right areas. It enhances the comfort and security of the shoe.

All Out Charge size and fit

The fit is regular in the heel and midfoot while the forefoot is generous in width and volume. Merrell caters to the needs of a large number of runners with this kind of fit. The company offers the standard medium width for this shoe. It is also of standard shoe length and is available in sizes 6 to 14 for the men’s and 4 to 11 for the women’s.


The outsole of the Merrell All Out Charge is very aggressive. It has 5mm multi-directional and rounded lugs that simply deliver a serious bite on a wide variety of trail surfaces. Merrell’s M Select Grip has proven traction and durability that should allow runners to enjoy the All Out Charge for a reasonably long time.


The UniFly midsole is a full-length EVA with Merrell-exclusive materials and technology that enhance midsole durability and responsiveness in a lightweight foam. While the cushioning has been increased in many of the All Out line of shoes, the UniFly still offers adequate proprioception or ground feel. Thus, the right mix of protection and connection starts with this midsole. A molded nylon midfoot insert keeps the run stable without being intrusive for neutral runners.


The HyperWrap 360 Degrees Fit System uses a combination of really breathable upper, synthetic overlays, and small nylon strips that are directly connected to the sole. As the entire upper is connected to the sole, there is an enhanced wraparound feel and excellent security in the most natural way. A gusseted tongue keeps off trail debris while a traditional lace-up closure personalizes fit and comfort.
