{{DISPLAYTITLE:Adidas Energy Boost 2 Review}}
The [http://www.zappos.com/adidas-energy-boost Adidas Energy Boost] 2 has a new material in the midsole (see 'Adidas Boost Foam' below) which changes how this shoe feels. The Energy Boost is immediately comfortable and the foam makes a noticeable difference to the ride. Sadly the Boost is a traditional design, with the typical raised heel and I would not normally recommend considering it. However, because the boost foam works so well, and because removing the insole reduces the drop to 7mm, I think it's worth considering. The insole is about 3mm in the forefoot and 5mm at the heel. Without that extra, the shoe is 14mm/21mm. Note that the Boost and the Boost 2 are virtually identical. I could not find any differences other than the "2" on the label. I've rated the Adios as "worth considering." {{H:WhatToLookForInShoes}}

* {{H:flexibility}}. The Boost is less flexible that I would have expected, partly because the foam does not have any grooves, and partly because of the extensive outsole.
* {{H:outsole}}. There is a hard rubber covering most of the contact area of the shoe, which improves longevity.
* {{H:shape}}. The shoe is does not match the shape of the human foot, so [[Shoe DissectionModifications| cutting open the toe box for comfort]] is a good idea.{{H:TryCuttingShoes}}
* {{H:upper}}. The upper is inflexible and fairly thick, with poor breathability compared with most shoes. There is a plastic 'skeleton' over the shoe from the ball of the foot back which adds weight and reduces comfort without seeming to add much value. However, it never caused me any discomfort.
* {{H:tongue}}. The Boost has a tongue that is partially attached to either side of the upper. I found that this worked well, as it felt like a conventional tongue that stayed in place perfectly. The tongue has thick, soft padding.
