Adidas Ultraboost 21 Womens Running Shoes

Blending several advanced attributes, the Adidas Ultraboost 21 Women's Running Shoes have a lively and enthusiastic character that infuses vigour into any training session or race.

A high rebound Boost midsole combines with its inbuilt LEP torsion system to deliver an energetic spring, propelling the runner towards PBs and podium finishes. This midsole is plush and shock-absorbing, increasing comfort and reducing fatigue on even the longest of runs across the harshest surfaces. Underneath the midsole, the Continental rubber Stretchweb outsole provides traction and control whatever the underfoot conditions.

Primeblue fibres, realised via recycled Parley Ocean Plastic that is trawled from the sea, make up the Primeknit upper. This woven upper construction is lightweight, highly breathable and cosily hugs the foot with a sock-like fit. The upper is complemented by the ergonomic heel construction that supports the rear of the foot to eliminate slipping, while the lace closure system tightens evenly to hold the foot without causing any pressure hotspots.
