Review - adidas ultraboost 20 The first thought when putting on is an amazing lacing system, very responsive, on the clouds. what I'm used to. Shoe durability - 2 miles in the shoe helped power transfer and cushioning was excellent. Breathability is way better than adrenaline. Compared to adrenaline rushes. I feel like this is a shoe that you can wear longer and retain energy for longer. Overall the shoes look amazing and work fantastic. I'm not sure I would pay for them again. Adidas, you need to work on the pricing.
