KEEN Arroyo II branding

Non-marking rubber outsole of Keen's Arroyo II

KEEN Arroyo II lugs

The non-marking, carbon rubber outsole of the Arroyo II is both tough and flexible. It’s constructed with low-profile, 4mm lugs which make the sandal bite into most surfaces. Their multi-directional form and systematic placement on the outsole allow traction from practically every angle.

KEEN Arroyo II arch zone

The outsole’s arch zone is curved, which exposes a portion of the midsole. This exposed part helps the midsole in giving the sandal flexibility.

Keen’s comfortable and sturdy midsole

With its dual-density, compression-molded, EVA midsole, the Arroyo II sandal absorbs shock upon landing. This midsole also gives wearers torsion stability as it comes embedded with an ESS shank. 

KEEN Arroyo II forefoot midsole

Resting on the bottom of the sandal’s interior is a removable, Metatomical EVA footbed that provides extra cushioning. It’s also perforated, which makes the insole quick-drying and breathable at the same time.

The S3 in KEEN’s S3 heel support structure refers to shock, stability and suspension. This component dissipates shock from the heel while keeping it stable. It also lessens the risk of sprained ankles.

Breathable upper on the Arroyo II 

The KEEN Arroyo II’s upper is made of waterproof leather and features vent holes and mesh webbing which provide breathability. Pull tabs are also present in the upper for on-and-off convenience. 

KEEN Arroyo II waterproof technology

The upper’s lacing system, which primarily gives wearers ankle support, is made up of quick laces, hook eyelets, and a clip mechanism. The uppermost hook eyelets are actually part of a single-build strap which hugs the heel part of the sandal. This strap adjusts the fit of the heel zone depending on the tightness applied on the laces inserted in the uppermost hook eyelets.
