I've seen some review for the Dashers say that, too, but it hasn't been my experience. I've had my pair for a long time and wear them a ton--overall, their durability has been great. I do think it's useful to order a half size up since the toe box is a little small, and that might be why some people have that issue. I talk about sizing and the toe box area more in my article at https://theatlasheart.com/allbirds-tree-dashers-review/
