The differences between the Pure Boost and the Ultra Boost are subtle, but they do exist. The Pure Boost has all the cushioning of the Ultra in the midsole, but it’s a significantly lighter shoe at 10.4 oz for a men’s size 10 in comparison to the Ultra’s 10.9. These are fractions of ounces, yet they do make for a lighter feel. The Pure Boost also has greater support in the upper for the quicker starting and stopping of shorter runs on pavement versus more long-distance training. Speaking of pavement, what makes this shoe such a top contender as one of the best for standing all day is the fact that it’s designed to be worn in an urban setting. The extra support in the upper and the more flexible outsole both lend itself to being one of the best shoes for standing on concrete. Meanwhile, Adidas’ style and versatility mean you can go from standing to walking to running through the city without missing a beat.
