—01. Techfit upper.
The variety of Adidas shoes available featuring Boost technology is quite impressive. Their Pure and Ultra Boost soles are certainly standouts, but the less minimal aesthetic of the Energy Boost caught my eye and pulled me in. It's the first time I've worn any shoes with the innovative foam cushioning, and I am pretty impressed with the level of comfort. This particular model also features a Torsion midsole and Techfit upper, which combine for a great feel, inside and out.
