Adidas Ultra Boost Men's Running Shoes Black/Red

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.
