Adidas Ultra Boost Women's Running Shoes Purple

The latest evolution in the esteemed Boost line, adidas have described the Ultra Boost as 'the greatest running shoe ever.' Engineered with a full-length boost™ midsole, the shoe keeps every step charged with an endless supply of light, fast energy for an incredibly responsive ground feel in even the coldest of weather. The TORSION® SYSTEM supports the midfoot while allowing for independent movement between the forefoot and highly-elastic heel, which features an external counter for natural Achilles movement and increased stability. Meanwhile, a stretch web outsole adapts and stretches with your foot strike and movement for further energy-harnessing power as you clock up the miles. To cap it off, a seamless and stretchy Primeknit upper adapts to the foot's natural expansion and helps reduce irritation, while an Ultralight sock liner ensures a perfectly comfortable fit.
