Bottom line

The KEEN Arroyo II is a reasonably priced, comfortable hiking sandal that greatly impressed users with its durability and versatility. It’s a grippy footwear that holds its ground on different types of surfaces. It is also easy to clean and dry. Preferred orthotics by wearers also fit the interior pretty nicely.

There were, however, users that came away dissatisfied with the sandal’s lack of steadiness due primarily to its elastic laces. Further compounding the negativity that surrounds the Arroyo II are the sandal’s underperformance against debris.

Good to know

  • The Arroyo II hiking sandal from KEEN is a waterproof, closed-toe option with a hydrophobic mesh. Across the leather upper are ample vent holes which add to its breathability.
  • The sandal features extra stretchy, adjustable speed laces which allow wearers to achieve a custom fit. The laces are secured by a built-in clip mechanism.
  • The midsole is supportive as it is engineered with torsion stability ESS shank. The S3 heel support structure also contributes to the stability that the Arroyo II provides.
  • On its rubber outsole are low-profile lugs that provide surface traction. They are multi-directional and non-marking to boot.

The KEEN Arroyo II is a shoe-like sandal for men and women. Its quick lace system plays a virtually exclusive role in giving wearers a secure fit. A strap that's connected to the front closure runs around the ankle for support.

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.

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.

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. Torsion stability refers to the steadiness of the wearer’s balance when performing actions that require twisting and tilting of the foot. 

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.

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. 

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.

  • This product is succeeded by the Arroyo III.
  • It was formerly known as the Taos.
  • Keen recommends the use of leather cleaner and conditioner to improve Arroyo II’s longevity.
