Size and fit

The Merrell All Out Blaze Aero Sport is a low-top shoe engineered for men and women. It uses a proprietary Omni-Fit lacing system, which grants a customized and glove-like lockdown. A molded counter made of thermoplastic polyurethane (TPU) is found at the rearfoot zone to lock the wearer’s heel down.

Outsole

This Merrell shoe for outdoor enthusiasts comes with a Vibram outsole. It uses a pattern of 5mm rectangular and oval-shaped lugs along its profile grip on a wide variety of surfaces. It has a central channel, which helps disperse water and debris for optimal traction. The outsole’s rear end houses several grooves to give added control when going downhill. Its front tip extends upward to prevent the user’s toes from getting stubbed.

Midsole

The Merrell All Out Blaze Aero Sport is able to supply speed hikers with cushioning, thanks to its UniFly midsole. It is made of a foam material with shock-absorbing pads positioned in the heel and forefoot zones. This trademarked technology also yields rebound and stability. Moreover, the shoe’s footbed grants extra arch support and comfort underfoot.

Upper

The Merrell All Out Blaze is equipped with a vegan-friendly upper made of synthetic fabric. It is lined with a layer of mesh, granting breathability for warm environments. Its forefoot region contains a rubberized cap for added robustness and trail protection.

This Merrell offering uses a series of fabric loops and metal eyelets to manage its fit. This lacing system is connected to a counter at the rearfoot area for added heel support. The shoe comes with a bellows tongue to prevent debris from entering it. Moreover, a pull tab is found at the back to facilitate easy on and off.

Merrell All Out Blaze Aero Sport vs. Adidas Terrex AX3

Speed hikers may consider both the Adidas Terrex AX3 and the All Out Blaze Aero Sport for their adventures. These lightweight below-the-ankle shoes are geared towards those who want to move fast on the trail. They also come with various features that help individuals perform in this kind of outdoor activity. Shown below are several qualities that differentiate these offerings apart.

Upper. The Adidas Terrex AX3 uses a mesh upper reinforced with synthetic overlays. It is lined with soft textile fabric, granting the user a comfortable and breathable in-shoe environment. The forefoot zone houses a molded thermoplastic polyurethane (TPU) cap to render protection from accidental bumps. The Merrell All Out Blaze Aero Sport is also breathable with its upper made of synthetic material. Unlike the Terrex AX3, this shoe, however, is quick-drying. This feature makes it an effective water hiking shoe.

Weight. The Merrell All Out Blaze is slightly lighter than the Terrex AX3. 

Closure. The Adidas Terrex AX3 is able to give wearers a personalized fit, thanks to its quick lacing system. It employs a series of loops and eyelets to facilitate fit management. Meanwhile, the Merrell All Out Blaze Aero Sport is equipped with a conventional lacing system, which allows users to have a customized fit.

Outsole. Adidas furnished the Terrex AX3 with a Continental outsole to help users traverse tricky surfaces. It uses an aggressive lug pattern, which bites down on most types of terrain. A heel brake is incorporated into its design for added descent control. The Merrell All Out Blaze Aero Sport gives these grip-centric benefits, via its Vibram rubber outsole.
