*b* Experience a run which is lighter, faster & with more energy. Experience a new performance with the adidas Energy Boost 2 ESM Running Shoes.*b* This is an evolution of running which is defined by the Energy Capsule Boost Midsole. Constructed from small polyurethane capsules which are fused together with high pressure steam, your every step now becomes charged as the Boost midsole absorbs some of the energy from your foot strike & charges it into forward momentum. Offering 30% more temperate resistance than standard EVA found in running shoes, this results in the structure being maintained, as well as enhanced performance & durability. Quite simply, the life of your trainers just got longer so you can add more miles. Although this innovative feature will boost your running, an array of other luxuries combine to offer something special in your quest for a PB. The lightweight upper is supported by Techfit material – created for natural, flexible support & a seamless, sock-like fit. Running over the sole & the highly durable outsole rubber offers great damage resistance & works alongside the Torsion System for added strength with every strike you make. As a further enhancement to these running shoes & your training, they are also compatible with the adidas mi Coach chip (not included) which fits discreetly beneath the inner sole. Your shoes now have the ability to report back on all your progress in training & on race day including statistics such as distance, speed & calories. These are all recorded & can be monitored by simply connecting the mi Coach chip to your PC or iPhone. For athletes who value the look of their shoes & like to stand out then the distinct solar red design is sure to give your running a boost. For a more refined addition, black & white complete the great look as part of the adidas running collection. *b* This running shoe weighs 282g (UK size 8).*b*""
