the keen website 's statement about 1\/2 size upping and the few post here regard the size concerned I a bit , so I would like to place my input by say for I it be true to size . the toe have a gap , but barely . and it really do have a sneaker feel to it with sandal comfort . one thing odd be that the right and leave shoe fit differently in appearance . could be my foot . for example ... the right small toe be cover under a strap and the left small toe be the only open toe . odd . give they a go for the day and I find it to be comfortable .
