    Hiking Sandals

    Made of lightweight materials. They don't have much top-of-the-foot coverage so they're mostly suitable for well-maintained trails and summer hikes. Also useful for crossing rivers and streams. They come in open and closed-toe designs. See the best hiking sandals.

    Hiking Shoes

    The low-cut equivalent of hiking boots. Comfort is paramount in the creation of these shoes so they often have flexible materials. Generally used for day hikes. See hiking shoes.

    Hiking Boots

    Mid to high-cut models designed for more aggressive hikes and backpacking. See hiking boots.

    Mountaineering Boots

    Specialized footwear. Often insulated and used in technical routes, ice climbing or expeditions. See mountaineering boots.

    Good to know

    For hikes that won't last for more than a day, go with hiking sandals or hiking shoes. Tackling trails with greater challenges will require hiking boots or mountaineering boots.

8 reasons to buy

  • The Keen Arroyo II got excellent remarks from satisfied owners for its sturdy build.
  • Many owners loved the sandal’s reasonable price tag.
  • Quite a number of people, including an expert reviewer, adored the sandal for its versatility. They said that it isn’t just for outdoor adventures, but also for casual use.
  • In terms of comfort, many users were truly impressed with the second edition of the Keen Arroyo.
  • This sandal is easy to clean, according to a handful of owners. A few of them even said it’s washer-friendly.
  • A moderate percentage of Keen Arroyo II’s user base lauded its grippy outsole which maintains great traction on most surfaces.
  • A handful of wearers were pleased with the Arroyo II’s quick-drying upper.
  • A few customers praised the sandal for its ability to accommodate their custom orthotics well. They said that insoles of their preference lock in place pretty snugly.

5 reasons not to buy

  • Some Keen loyalists found the Arroyo II’s not true-to-size fit disconcerting. Most of them had to reorder a half size smaller or bigger, and there were more people who went with the former.
  • A number of disappointed users were annoyed because they couldn’t shake off the debris while wearing the sandal.
  • A few female buyers protested about its lack of color variation. Apparently, one color—dull brown, according to an owner—simply is appalling.
  • A few owners weren’t too thrilled about the sandal’s lacing system. One of them said that the lace clips struggled to keep their grip and had to be adjusted numerous times.
  • One expert expressed his discontent with the elastic laces. He said that the Arroyo II lacks steadiness because of them.

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—whether in outdoor environments or urban settings. The materials used in creating the sandal make it 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 not true-to-size fit, measly color variation, and underperformance against debris.

    The Arroyo is a good design, but its flaws made us miss our Newport H2 or our Dozer sandals.

  • 75 / 100 | Alisonmlea

    These shoes will never replace a sturdy pair of walking boots, but they are a great option for walks on footpaths and they cope well with uneven ground and mud.

Updates to Keen Arroyo II

  • The Arroyo II is a waterproof, closed-toe sandal 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.

Keen Arroyo II size and fit

The Keen Arroyo II is a shoe-like sandal that comes in standard width for both men and women. The men’s sizes are from 7 to 17, with half sizes until 11.5. The women’s version, on the other hand, comes in whole and half sizes from 5 to 11. The sandal runs half a size larger, and Keen suggests getting a half size down than the buyer’s normal size. The sandal’s quick lace system plays a virtually exclusive role in giving wearers a secure fit.

Outsole

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.

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. 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.

Upper

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.

Additional Info

  • The Keen Arroyo II was formerly known as the Taos.
  • Keen recommends the use of leather cleaner and conditioner to improve Arroyo II’s longevity.
