When you're premiering something big it's customary to roll out the red carpet. Adidas figured that wasn't necessary, because no red carpet can match the plush underfoot comfort of their new UltraBOOST 19 Shoe. Offering lots of comfort, cushioning, and responsive energy return for everything from speedy track workouts to long weekend training runs, the UltraBOOST 19 is the most road-ready iteration of this shoe yet. Shedding its image as a lifestyle/running hybrid, this shoe maintains the same style as previous versions but offers the performance and durability you need to hammer down some serious miles. It all starts with the improved Boost midsole, which offers more responsive cushioning than ever before. Most of it is centered in the heel, making this shoe ideal for those long days when you end up falling back in your stride. Boost also offers some of the highest levels of energy return on the market, ensuring that every run will have an added dose of energy that'll help you find that extra gear, even when you're starting to break down. The upper of this shoe is built with a flexible Primeknit material that wraps your foot in snug support, giving you both comfort and a secure fit for endless miles. The supportive midfoot cage has also been updated to be more flexible and forgiving, so you won't feel such a rigid structure when you're rounding quick city corners. Add on a flexible, high-traction Continental rubber outsole that'll grip those same tight corners on even the rainiest days, and you've got a shoe that can go the distance with comfort and style.
