The Under Armour Surge 2 seeks to become a sturdier update compared to the original Surge model. The silhouette of version 2, though still breathable, now has increased volume and thickness to the weave to accentuate durability. A mix of stitch-on and printed overlays reinforce the fabrics, though seamless coverage is also at the forefront of the construction. A pod-outsole configuration delivers traction and extra bounce to the step.

Size and fit

Runners are welcome to get a pair of the Surge 2 with their usual choices of size in mind because it has a true-to-size distinction via the use of standard sizing schemes. However, if one wants to be sure about the quality of the in-shoe experience, then personal testing of this running shoe can help to alleviate those concerns.

A semi-curved platform and a slightly stretchy upper unit seek to follow the natural curvature of the human foot, thus aiming for a secure yet accommodating wrap.


The prominent impact points of the heel and forefoot are covered with rubber. This compound is meant to shield these areas of the platform from the abrasive nature of the ground. It also has a grippy construction that allows it to adhere to the ground and provide slip-free steps to the runner.

Ground-contact foam fills the rest of the areas that aren’t covered with rubber. These sections have pod-like protrusions to assist the rubber when it comes to doling out surface grip.

Flex grooves allow the sole unit to bend in tandem with the foot as it moves through the gait cycle. The forefoot lift is the part of the gait that stands to benefit from these elements as it involves foot flexibility.


Underfoot cushioning is the task of the full-length ethylene vinyl acetate (EVA) foam. This material offers a lightweight yet responsive ride. It even has a shock-attenuating capacity that mitigates landing impact. EVA is used by many running shoe series, including the Hoka One One Clifton.

A raised midfoot section aims to support the arch at all times. Giving some attention to the arch can ease tension during the run.

An EVA sockliner is placed right above the main cushioning unit. The job of this add-on is to provide some softness for the underfoot. Also, it can be removed or replaced with a new one if the wearer wants to do so.


A mesh material is used for the upper unit of the Under Armour Surge 2 and it is meant to cover the foot at all times and keep it secure as it moves through the gait cycle. A thick-weave construction with open ventilation holes signifies durability and preservation of breathability.

Printed overlays grace the sides, the instep, and the forefoot while a stitch-on variant reinforces the heel part.
