Under Armour Micro G Engage 2 Running Shoes - SS15 Synthetic-and-mesh Increased Mobility - A slimmer, athletic build improves mobility by eliminating the bulk of additional, superfluous fabrics. Breathable Mesh Upper - Allows air to fully permeate the shoe's interior, encouraging an environment that is cooler, drier and altogether more pleasant. Foam Overlays - Straddle the upper to reinforce its structural integrity without adding undue weight. Internal TPU Heel Counter - Secures the foot firmly in place for a more reliable and improved lockdown. Full Length 4D Foam Sockliner - Conforms to the shape of the wearer's foot to deliver a secure, customisable and adaptive fit that reduces slippage.
