    As far as snow goes, this is where the shoe really excels. When I was running uphill, downhill and cross on snow and ice, there was no problem. I felt good bite and never slipped once.

    The waterproof upper has a minimal, sleek design and that signature Merrell fit, which will appeal to runners who like a roomy and flexible forefoot.

    Merrell’s All Out Terra Ice is a sturdy winter runner that shines on verglassed road and trails. The synthetic outer repels the elements and the sturdy front rand protects the digits from hidden toe bashers lurking beneath the white stuff.

    One obvious quirk: the loose heel gave an unusually insecure rear-foot fit—a strange feeling but not a deal breaker.

  • Richard Shop Zappos
    You also have this Trail Protect Pad that'll give you great underfoot durability and protection.

Updates to All Out Terra Ice

Merrell’s popular All Out Terra line brings 9 carbide spikes in the outsole to make running on ice such a treat in the Terra Ice. By adding these tungsten-made spikes, the highly-sought performance of the All Terra in the outdoors becomes even more so during winter season.

More than just the spikes, the outsole is fitted with very aggressive 6mm rubber lugs for the ultimate outdoor grip on wet rocks, technical trail, gravel, and even mud.

The new inner sock, just like the one found in the trail version, offers exceptional wraparound feel and enhanced foot security. Piling on the miles in winter is more comfortable with the interior plush feel that is enhanced by this cozy inner sock.

As cushioning is enhanced in the All Out series, which is quite evident in the All Out Terra Ice, most runners will still feel decent flexibility and adequate close to the ground experience for better feedback.

All Out Terra Ice size and fit

The All Out Terra Ice delivers Merrell’s signature close fit in the heel and midfoot with a roomy toe box. With the kind of secured feel in the right areas, runners who love speed should be more confident in their strides. On the other hand, the roomy toe box caters to the need of different runners and provides a very plush room for the toes to splay. Available widths are D for the men’s and B for the women’s. Sizes are on the money with the All Out Terra Ice. Options can be 6 to 14 for the men’s and 5 to 11 for the women’s.

Outsole

Merrell incorporates the spectacular aggressiveness of 6mm lugs and the stickiness of the Vibram outsole for an incredible grip on different surfaces. As if that were not enough, 9 carbide spikes are also located underfoot to make the Terra Ice a serious operator in icy or snowy conditions.

Midsole

A Trail Protect Pad is located just above the outsole for a little cushioning and enhanced underfoot protection.

Upper

The upper of the All Out Terra is made of synthetic mesh for great breathability and TPU overlays for better structure and support. Merrell also uses a waterproofing membrane below the mesh upper to fight off water or snow. An M-Select Dry Membrane keeps the interior dry as it wicks away moisture. Since there is a chance that the runner faces low-visibility conditions during winter, the reflective materials will be very handy. The removable footbed adds step-in comfort and secure feel and can also be replaced with customized orthotics.
