Features
  • Made for water. Chaco build the Z/1 for water: quick-drying webbing straps, 360º adjustability wet or dry, and a ChacoGrip™ compound optimized for wet traction.
  • 360º adjustable fit. One continuous strap runs through the footbed and around the whole foot, so the fit is tuned at every contact point instead of at a single buckle.
  • Podiatrist-certified LUVSEAT™ footbed. Chaco's signature LUVSEAT™ footbed is certified by podiatrists and holds the arch in alignment through a full day on foot.
  • ChacoGrip™ outsole. A non-marking ChacoGrip™ rubber compound on a 3.5 mm lug pattern, built to grip river rock, wet trail and loose ground.
  • Repairable, recycled webbing. The webbing is made with REPREVE® recycled fibre, and the sandal can be resoled or re-strapped at Chaco's ReChaco factory in Michigan rather than replaced.

Water use

Built for water

Best for

Is this right for you?

Rivers and lake days

Chaco classify the Z/1 as made for water. The straps dry fast, the 360º adjustment holds the foot when wet, and the ChacoGrip™ outsole is optimized for wet traction on river rock.

Not for: Not a reef or swim shoe — the toe is open, so rock and shell reach your foot. All sandals and water shoes

Day hiking and trails

Chaco list the Z/Sandal range as made for trails, and the 3.5 mm lug ChacoGrip™ outsole over a podiatrist-certified LUVSEAT™ footbed carries a day on trail.

Not for: Not for loaded backpacking or scree, where an open toe and a strap upper leave too much exposed. Shop all Chaco

Travel and every day

Chaco list the range as made for travel and for every day; the Z/1 packs flat, adjusts to a swollen travel foot and goes from the walk to dinner.

Not for: An open sandal with no insulation — warm-weather footwear only. Women's Z/1 Classic

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
Do these run true to size?

Chaco publish the Z/1 Classic in whole US men's sizes 7–15 in a medium width, and publish no true-to-size note for it. The single strap runs through the footbed and adjusts around the whole foot, so a little in-between-size slack is taken up by tightening rather than by changing size.

Can I get them wet?

Yes — Chaco build the Z/1 for water and publish it as made for water. The polyester webbing straps dry quickly and the ChacoGrip™ outsole is optimized for wet traction.

How do I clean them?

Chaco publish no cleaning instructions on the Z/1 Classic product page. The upper is polyester webbing over a PU footbed, so rinse with fresh water after salt water, sand or chlorine, wash the webbing with mild soap and a soft brush, and air dry at room temperature away from direct heat.

Will the footbed mould to my foot?

The LUVSEAT™ is a moulded PU platform with a fixed arch shape — it supports the arch rather than taking an impression of your foot, so the contour you feel on the first wear is the one it keeps. Chaco publish no break-in or moulding claim for it.

Are they good for wide feet?

Chaco build this version in a medium width only, and publish a separate wide-width Z/1 Classic for feet that need more room. The strap adjusts around the whole foot, which helps across the instep, but the footbed itself is a medium width.
