    This product is for…

    Runners prone to big-toe blisters, especially on steep or technical terrain where the big toe works hard during push-off and climbing. Also suits those who want a more stable foot feel inside the shoe without committing to a full toe sock.

    Worth noting…

    The split-toe design feels unusual at first but hosts say it quickly makes sense, particularly on climbs. Breathability on long efforts is also called out, though notes are otherwise one-sided positive with no criticism.
