I waited a long time to try these (a former Keen/Birkinstock costomer). Nothing else out there offers the support, comfort and durability of Chacos. Great product.

  • “I ordered a pair of 9 Wide Chacos. The box indicates that the size is 9 Wide, but the sandals are marked M-9 n the back of the sole. There is no slack in the straps after adjustment.

    Are the shoes 9 Wide?”
    Asked by hobbit feet from texas on 6/18/2014 9:21:35 PM
    • My 9-Wide shoes are marked "- M9 -" on the back. I usually wear 9EE and I have about 2 inches of slack after I tighten the straps and the shoes fit well; they are not too narrow.

    • I have no clue! I purchased two pair, but mine are size 11. Great sandals but take time to break in.

    • It sounds like you have a pair of 9 Medium sandals. I wear a 9 Medium and actually trimmed the tightening strap as it was trailing on the ground. You may want to do an exchange. STP takes care of postage.

    • My husbands say M 13 and he ordered a size 13 Chaco--so all I can tell you is he ordered a size 13 and than is what his say!!

    • In Chacos sizing - = wide and .= medium, therefore
      a M-9 is a men's wide 9
      a M.9 is a men's medium 9

    Thank you.”

    • I have approx. the same size foot and the 10 fits me fine. I have a low arch. Bare foot I have plenty of room but wearing socks it is a bit snug, the sandal is 29 cm from heel to toe and 10.2 at the widest point.

About Chaco

There's a good reason why Chaco shoes have maintained a devoted following of adventurous souls (proudly known as Chaconians) for more than 25 years. From the incredible, arch-supporting footbed to the totally unique strap configuration, Chaco sandals fit like a glove and provide amazing support. Originally created by Mark Paigen in 1989, Chaco sandals have since evolved from a single pair of “Ultimate Sport Sandals” into an array of adventure-ready footwear products, including Chaco boots, sneakers and even clogs. Plus, to reduce waste and help loyal Chaconians get more miles out of their favorite kicks, this brand has even introduced the ReChaco Project, which allows customers to send in their worn or damaged sandals to be repaired.
