The Adidas Ultraboost Light is a daily training shoe with a highly cushioned heel and a firmer forefoot. The midsole is full-length Light Boost, which is a lighter and slightly firmer version of normal Boost. There is a large amount of this in the heel, which provides a softer rearfoot landing.

Fit – The adidas CrazyLight Boost 2016 runs true to size so that's what I'd recommend. It's narrow at the base of the forefoot so wide footers may want to consider going up 1/2 size or skipping the shoe altogether.
