I had already purchased two pairs of Cloud Step 10s—one in EU size 39 and one in 43. They are very comfortable, with excellent cushioning. However, I found that the size 43 (US 9.5)—my usual size—ran a bit large. When the Archlite Pro came out, I decided to get a size 42, but I’ve noticed they fit a bit tight. This is because I have high-volume toes; I need a toe box that is both wide and—above all—high to avoid discomfort. The Archlite fits more snugly than the Cloud Step 10; it is firmer and much more stable. I admire the material quality and the finish—both are outstanding. I hope the brand continues to maintain these standards regarding both price and quality.
