Just as Nike has been able to strip away weight and add ventilation to models using its Hyperfuse construction, adidas has offered a similarly slight and breathable material composite in the form of SprintFrame and SprintWeb technologies. The latest model to employ this featherweight combo is the aptly named adidas aidZero Feather, a sleek lowtop that rides a adiPrene+ sole but still only weighs 6.7 oz for a US mens size 9! The running equivalent of the adiZero Crazy Light, the adidas Feather is available now at select Three Stripes retailers and Shopadidas. via HB
