Evaluation For a brand that has such good road-racing shoes, it’s a surprise that Adidas hasn’t been able to make one of the top performance trainers as well. The Rotterdam will elevate the company to that upper level. It’s a lighter, more performance-oriented version of the much-loved Boston. The Rotterdam has the same light, well-cushioned midsole as the Boston. And even though it doesn’t have any added stability features, it’s still reasonably stable, with some medial support due to a stability shank in the midfoot.
But the major difference between the Rotterdam and the Boston is the upper and outsole. The Rotterdam’s light, flexible outsole has thermoplastic pieces embedded right into the midsole, while its mesh upper is extremely light. Just like the Boston, our weartesters loved the Rotterdam, and praised its ride and flexibility. And despite it being a trainer, many felt they could race in it.
In short If you’re fast and efficient, you’ll love this shoe. For most runners, it’s not a daily trainer, but it’s bound to be on a few marathon runners’ feet or end up as a second shoe for speedwork.
Try it on if you liked Asics Gel DS Trainer (£80); Mizuno Wave Precision (£60)
