As a neutral shoe, the Cumulus 20 can feel it is truly made for all runners. But it does come with a smaller forefoot which will remove some of the freedom you might have been used to from the previous version. However, this makes the shoes slightly more responsive and better at higher speeds. Still, they are true to size and I don’t need to go half a size up for the right fit. With a lightweight construction, they also maintain a flexible profile, even with the gel insertions of the midsole.
