With a narrow profile, the shoes are recommended for running at any speed. They are made with added perforations which means their breathability is at a high level keeping your feet cooler. But even if the shoes are narrower, they still represent a solution which is stretchy and which works great for lateral support when needed. With average cushioning thickness around the ankles, they are also comfortable even when you run for hours. If you want to use them for performance training, you also need to know that the shoes do not require a break in period.
