  • Constricting fit: The Ultraboost Winter.RDY is not for runners with wider feet. According to some testers, the forefoot is "narrow and tight" and feels "cramped."
  • Blisters: Several reviewers reported that they got "unforgivable blisters" because the shoe is too tight in the ankle.
  • Not enough water-resistance: There have been reports that the water-resistant upper did not perform as expected. A few said their socks were damp after running several miles in the rain.

Bottom line

Designed for all-weather athletes, the Ultraboost Winter.RDY features a water-repellent upper to keep you going in light rain and snow. A "winterized" version of the popular Ultraboost, this shoe features the responsive Adidas Boost midsole and a durable rubber outsole that gives traction on rough and wet grounds.

Though it is ready to keep your feet warm in cold weather, the upper of the Ultraboost Winter.RDY will not keep your feet dry on puddles and heavy rain.
