Chacos are adjustable sport sandals built for rivers, trails, and long days on your feet. Colorado river guide Mark Paigen started the company in 1989 to solve one problem: footwear that stayed put in moving water. Two decisions matter more than color before you buy. Do you want the toe loop? And this label makes whole sizes only, which changes how you order. Below: where to buy a genuine set, what separates the models, and the mistakes that send first-time owners back to the returns counter.

Who Actually Needs Chacos
A Chaco is an open-toed sport sandal built around one continuous strap that threads through the midsole and wraps the arch, holding your foot without buckles digging in at separate points. That single-loop design is the whole idea, spreading tension along the strap instead of concentrating it at a buckle.
Who gets the most out of them: hikers who cross creeks, rafters and kayakers, camp staff, travelers packing one shoe, and anyone wanting real arch support in an open design. The LUVSEAT footbed carries the American Podiatric Medical Association Seal of Acceptance, which almost no open-toe sandal can claim. Same structural argument people make for supportive running shoes, applied to summer footwear.
Skip them if you want the soft give of flip-flops: the platform is firm and molded, not cushioned foam. The webbing also prints a hard-edged tan line that lasts all season, so the layout you pick is effectively permanent until October.
Buying Criteria: What Separates Good Chacos From Bad
The model decision comes down to one question: do you want the toe loop?
Z/1 versus Z/2. The Z/1 uses the original single-strap layout. The Z/2 adds a loop around the big toe, which stops your foot sliding sideways on wet rock and in current. That matters if you scramble or wade, though the loop takes a week or two to stop feeling odd.
Whole sizes, widths, and the size chart
There are no half sizes in the adult range. At a 9.5 you are choosing between a 9 and a 10, so measure and check the official size chart rather than trusting your usual number. The webbing tightens but sole length is fixed, which is why sizing down beats sizing up. Wide widths exist on select models, so confirm before ordering if you have broad feet.
Cloud versus Classic platform. The LUVSEAT platform is injection-molded polyurethane, a denser material than the EVA foam most sandals use, so it holds its contour for years. The Z/Cloud adds a softer CushZ top layer, better for pavement than slick rock. If you want a cork bed that molds to your foot, Birkenstocks are the closer comparison.
Custom versus stock. The MyChacos builder lets you pick webbing pattern, hardware, and width, but those pairs are built to order, slower to arrive, and generally final sale. Buy stock first, go custom once you know your size.
| Model | Toe loop | Best for | Feel |
|---|---|---|---|
| Z/1 | No | Trails, town, travel | Firm, structured |
| Z/2 | Yes | Creek crossings, rafting | Firm, locked in |
| Z/Cloud | Both versions | Long pavement days | Softer top layer |
| Chillos Slide | No strap system | Camp, post-hike recovery | Loose and light |
Strap adjustment defeats more first-time owners than anything else. This sequence works.
- Loosen the entire length first. Pull slack through every slot before your foot goes in.
- Set your arch on the raised section. The high point belongs under your arch, not behind it.
- Move slack toward the heel, leaving a finger’s width of room. It is one continuous piece, so work the excess along it in stages until your heel stays planted.
- Break them in indoors. Short wears on carpet for a week, before sole scuffing makes a return harder.
When to Replace Chacos
Worn a few times a week, one set usually gives several summers before the tread goes smooth, though terrain matters more than time. Three signals it is done: lugs worn flat under the ball of the foot, frayed webbing that no longer grips in the buckle, and a platform polished slick where the heel lands.
Here the cost math turns unusual. The brand runs a paid repair program, ReChaco, that resoles worn sandals and replaces damaged webbing rather than forcing a replacement. Very few sandals at any price offer a factory resole at all, which changes how to read the sticker: a well-kept set gets rebuilt instead of binned.
To stretch the interval, rinse them after a salty or muddy day, never dry them on a radiator or hot dashboard, and rotate with a second set if you wear them daily. Retire them if the sole starts separating at the toe, since that gap spreads fast and puts a resole out of reach.
Buying Chacos Online: Retailer Comparison
Chaco sandals sell through a short list of authorized retailers online. The choice is between the full catalog, the easiest returns, and a discount on last season’s colorways.
Chacos.com and the MyChacos builder
The manufacturer site carries the full catalog, including seasonal colorways and limited runs that never reach third-party shops. It is also the only place to build your own pair and the only place to start a ReChaco resole order. Visit the official store for current stock and the size chart.
Amazon
The official storefront stocks men’s, women’s, and kids’ lines, and the review volume helps with sizing because owners note whether a model runs narrow. Buy there rather than from an unfamiliar marketplace seller, since counterfeits circulate on this label. Shop the brand page on Amazon for the current lineup.
Zappos, Sierra, and other authorized sellers
Zappos is the low-risk pick for a first purchase: free shipping and free returns are its standard policy, and you are guessing between two whole sizes. View the full lineup on Zappos. Sierra, formerly Sierra Trading Post, discounts past-season colorways, though size availability there is thin. Browse their current deals. Backcountry, Moosejaw, Nordstrom, and Nordstrom Rack round out the authorized list. Check the clearance inventory and filter by size first. On Poshmark and eBay you buy secondhand, so ask for a photo of the underside and treat a deep discount as a warning.
Buying Chacos Locally: Store by Store
Checking the fit in person matters more here than for most footwear, since you cannot split the difference between whole sizes.
REI and outdoor specialty shops
REI is the most reliable brick-and-mortar option, typically stocking the core Z/1 and Z/2 lines in the footwear area near hiking boots. Co-op members earn an annual member reward on eligible full-price purchases. Browse their selection online and use the store-availability filter before driving over. Independent paddling outfitters and regional shops such as Mountain High Outfitters and Sun & Ski sometimes stock widths the national chains skip.
Dick’s Sporting Goods, Academy Sports + Outdoors, Scheels, Bass Pro Shops, and DSW also list the label, though assortments run narrower and skew toward best-selling styles. Check availability on their site for your nearest location. Chaco outlet locations and factory sales clear past-season stock at the steepest discounts of the year, but sizes go fast and those sales are final. Call ahead.
Red Flags When Shopping for Chacos
Counterfeits on unfamiliar marketplaces. Fakes circulate through discount sites and social ads. Check for the embossed logo on the footbed and buy from authorized sellers. A price far below everyone else is the tell.
Sizing up because you land on a half size. The single most common ordering error. Too long beats slightly short only in theory, since a heel that slides forward will blister no matter how tight you cinch the webbing.
Assuming a lifetime guarantee. The warranty covers manufacturing defects for a limited period, not ordinary wear. Keep the receipt and treat the resole program as the plan for everything the warranty will not cover.
Best Chacos Right Now
Five picks covering the realistic use cases. Ranges reflect list pricing as of September 2026.
Best overall: Chaco Z/1 Classic. Original layout, polyester webbing, ChacoGrip outsole, LUVSEAT platform. Easiest version to get on and off. Around $100 to $110. Check price on Amazon
Best for rivers: Chaco Z/2 Classic. Identical build plus the toe loop. For stream crossings, kayaking, and slick riverbed rock. Around $105 to $115. Check price on Amazon
Best cushioned: Chaco Z/Cloud. Softer top layer over the same supportive base, for when the standard platform feels too rigid on pavement. Around $100 to $120. Check price on Amazon
Best budget: Chaco Chillos Slide. A lightweight slide for camp and post-hike recovery, competing with Crocs more than the Z-line. Around $45 to $55. Check price on Amazon
Best for kids: Chaco Z/1 EcoTread Kids. The adjustable strap system scaled down, with a recycled-rubber outsole. Around $55 to $65. Check price on Amazon
Settle the toe loop question first, since it decides between the Z/1 and Z/2. Then order your true whole size from a seller with easy returns and break them in indoors for a week. If you already own a worn set of Chacos, price a resole through the factory program before buying new.
Chacos Questions, Answered
Do Chacos come in half sizes?
No. The adult range is whole sizes only, so half-size wearers have to choose. Most do better going down, since the webbing tightens but sole length is fixed. Kids’ sizing runs on its own scale and does not map to adult numbers, which catches parents ordering for an in-between child.
Do Chacos work for flat feet or plantar fasciitis?
Often, yes. The LUVSEAT platform holds the American Podiatric Medical Association Seal of Acceptance, a program that reviews products for foot-health benefit, and it keeps its shape rather than collapsing, which is why it comes up for plantar fasciitis. Very flat feet are the exception, since the arch height can feel like too much.
Why do Chacos start to smell, and can you wash them?
Polyester webbing absorbs sweat and lake water, and odor builds where the strap meets the footbed. Wash them with mild soap and cool water by hand, or on a gentle cold cycle, then air dry completely. Never use a dryer or leave them in a hot car, since heat weakens the adhesive holding the layers together.
Are Chacos still made in the USA?
Most standard production moved overseas, but custom orders and factory resoles run through the company’s Rockford, Michigan operation. The label has belonged to Wolverine World Wide, the Michigan group behind Merrell and Saucony, since 2009.
