My Hyperdunks are loosening up around the ankle, becoming more flexible. The ankle rubbing problem is fading. These shoes should improve with further wear. They're just not an "out-of-the-box" kind of shoe. Wearers must break them in. Fortunately, they adapt to feet rather quick. After five workouts, I sense improvement.
Another upside for Hyperdunks, and basketball shoes in general, is that they provide great support when weightlifting. I forgot how valuable a good pair of hightops are when pushing free weights. They offer far better support than running shoes.
