COMFORT: Like virtually every Keen sandal I have ever worn, there is a moderately firm but forgiving contoured footbed. It’s a strength of this brand. The strap material is fairly soft polyester; they’re not rough or abrasive. A significant improvement is the size and shape of the toe bumper and the way the strap runs through it; it used to be a source of friction, but Keen reduced the size of the toe bumper. Instep view

Keen Zerraport II Reviews - Trailspace

KEEN has given its Zerraport II Sandal a bold psychedelic makeover. Following its recent collaboration with Engineered Garments, the outdoor footwear label, this time around, opted for a colorful ’70s-inspired iteration imagined by its Tokyo Design Center. Keen‘s Zerraport II is a successor to their Zerraport, which in turn is a successor to the long-discontinued hydro guide. https://www.trailspace.com/gear/keen/hydro-guide/ With the durability and the performance to keep up with young explorer, these fun, colourful kids' sandals are ready for any adventure. Trailspace's community of gear reviewers has field-tested and rated the top sport sandals. All SandalsFIT: The Zerraport II has a reasonably forgiving fit—my feet are E width in front, no problems with these sandals. They run true to size; I wear a men’s 11 1/2 or 12 in street shoes; the size 12 is a good fit for me.
