Review summary
Written by Augur from the 23 reviews analyzed
This running shoe is designed for runners looking for a smooth stride and optimal comfort on roads and paved paths. Users almost unanimously highlight the quality of its cushioning, which effectively absorbs shock, as well as its responsiveness that energizes each stride. Furthermore, the remarkable flexibility of its sole offers a very natural foot roll right from the first wear.… However, a few runners note that the outsole design tends to trap small stones during runs on gravel paths.
