I bought the Ultraboost 1.0 recently and was excited to try them, especially since I already own the Ultraboost 22 and Ultraboost Light and love both pairs. However, the fit of the Ultraboost 1.0 didn’t work for me. Even though the size is correct, the upper feels tighter and it causes discomfort and pressure on the top of my foot, which I don’t experience with the newer Ultraboost models. The overall comfort is simply not at the same level as what I’m used to. The quality is great as expected from Adidas, but the shape and fit just didn’t suit my feet. This might still be a great shoe for others, but personally it wasn’t the right fit for me.
