Astral Loyak AC Review

The Loyak AC is a minimalist, low-cut water shoe. They feature a thin sole, thin upper, and a tongue design that snugs them comfortably against the midfoot. Their siped rubber soles stick well on slick, wet rock. That traction, combined with the thin soles' excellent proprioception, gives them a great feel in and out of the water.

Performance Comparison

Comfort

The Loyak AC has a small but stretchy opening at the ankle and no real tongue. Instead, a sock-like cuff wraps around your foot as you slip it into the shoe. The footbed is foam but has a bumpy top that somehow lets your foot slip into the shoe easily. Once weighted, it keeps your foot in place.

The interior is mostly mesh and feels fine on bare feet with minimal stitching. With a thin sole and minimal heel-toe drop, you notice the undulations of the ground surface as you walk. We found that our feet had to work more than in more traditional, stiffer shoes for long walks over river cobbles. The Loyak AC favors a more flexible ride in exchange for foot protection. We had no problem portaging over giant boulders or wading through shallows, but we had to be more aware of where we placed our feet to avoid injury, at least compared to burlier shoes.

The upper materials and drainage ports on the front, back, and sides of the shoes make them excellent for transitioning in and out of water. With a snug fit, they let out water quickly and manage moisture well. After a day of boating, we liked that these were comfortable to wear barefoot right after getting off the water - a great quality in a shoe for hanging around camp on a raft trip.

Traction

The Loyak AC is one of the stickiest options we tested. They feature a siped G15 rubber outsole that is more than capable of carrying a boat across slick, wet rocks or walking over cobbles in murky shallows.

The relatively flat, non-aggressive lugs reminded us of approach shoes, which favor surface area over deep lugs that maintain traction on soft surfaces. Like approach shoes, the Loyak AC stick well to wet rocks and logs but suffer slightly in muddy conditions.

We noticed no significant loss of traction on firm dirt or duff on soft surfaces, but we started slipping more than we'd like on mud. The widely spaced lugs do clear easily, though, once they reach water, so it's easy to get the dirt off and restore traction on hard surfaces.

Warmth

The Loyak AC is mainly made of mesh and hydrophobic canvas with lots of drainage and minimal insulation. They rely on being adjustable enough to allow for adding insulation, like thick socks. While the lack of a tongue inhibits adjustability slightly, we didn't find that we had problems stuffing our feet in these shoes, even with thick socks. The AC version of the Loyak particularly focuses on breathability, making them even more chilly to wear in cold water.

The removable foam insole is relatively thick, at 7mm, compared to many shoes, and opens the shoe up quite a bit if you want maximum space for insulation. Our lead tester stuffed his feet in these shoes wearing thick wool socks under his drysuit socks and a thin polyester sock over his drysuit sock, maintaining warmth on a frigid fall morning paddle. The wide toe box characteristic of Astral shoes helps keep toes from feeling squished when packing in lots of insulation, but it all depends on how you choose to size your Loyaks.

Versatility

The Loyak AC is marketed as a casual shoe with serious whitewater chops. We totally agree with that. They are considerably more stylish and comfortable on land than booties and perform nearly as well in whitewater (provided you can insulate well enough on cold days).

We wore the Loyak AC hiking during testing, walking along steep mountain streams, boating, and around town. We would definitely not recommend them for canyoneering, but they'd do in a pinch as long as you took care not to tear them apart. We'd not hesitate to take them traveling as a primary boating shoe or even as a backup that also works great on hikes and around town. They also slip on easily, making them a stellar camp shoe.

We don't rate shoes on style, but using the Loyak AC for months, both on and off the water, has convinced us that it might be worth calling out these shoes as notable for their looks. Our testers frequently get compliments about these shoes, and their good looks make them especially versatile. For the price, you get not only a great water shoe, but a shoe that fits in at the bar and even at work.

Sensitivity

The thin, neutral soles of the Loyak AC are nearly as sensitive as some of the neoprene booties we tested. They provide excellent proprioception, enabling good balance and awareness of the terrain. The super-low profile of these shoes also made them excellent for swimming and wading, as they have a low drag in the water and allow feet to flex easily.

They feel similar to minimalist, barefoot-styled running shoes, especially with their relatively flat lugs. While there isn't much protection from the upper, the outsoles kept our feet happy when walking on sharp rocks.

Quality of Construction

While we loved wearing these, they are by no means burly, durable shoes. This version of the Loyak has even more mesh than the classic version, further identifying these as water shoes that should stay away from abrasive rocks and bush-whacking hikes.

Besides the considerations that come with mesh, the Loyak AC is very well constructed, with stitched and glued soles, clean lines, and noticeably high-quality craft. The rubber outsole wraps around the entire shoe, providing somewhat of a bumper to guard against punctures or abrasions. The AC version of the Loyak also makes the shoe lighter.

While the Loyak AC won't last particularly long in harsh, rockier environments, they'll offer longevity for kayaking or rafting. They are resistant to moisture damage with excellent drainage, and the snug fit does well at keeping out sand and debris that can abrade a shoe from the inside.

Should You Buy the Astral Loyak AC?

The Astral Loyak AC blew us away with how much performance we could squeeze out of such a tiny shoe. With super-grippy outsoles, a comfortable interior, and a snug fit, they keep feet happy on land, in a boat, and even outside a boat (accidentally or not). They offer good versatility and performance in a minimalist and stylish package for a very reasonable price. The Loyak AC gets high-value marks because it not only performs superbly in whitewater, but also works well for wet hikes and hanging around town. While booties can be slightly warmer and stickier, they don't have the on-land performance and foot protection (at least the bottom of the feet) of the Loyak. For considerably less than the premium-priced pairs, you can get a well-made, comfortable, and high-traction shoe for boating or just hanging around wet places.

What Other Water Shoes Should You Consider?

This shoe is hard to beat as an all-around jack of trades. However, a more durable shoe that offers more warmth and versatility is the Astral Brewer 2.0. This shoe feels more durable, even if it is a little less impressive for traction. If traction is less of a concern, the Brewer can save you some money and offer more versatility and durability for the long haul. If budget is a concern, or your needs are not as vast, you can save some money with the simple neoprene bootie design of the NRS Kicker Wetshoe. This shoe is warmer and more durable than the Loyak, but it isn't as versatile. Depending on your plans, it could save you money and keep your feet warmer.
