Product Description

Super Cute. Super Comfy.

Xero brings our Natural Movement fun and feeling to a “MaryJane” style shoe for women — the Cassie.

The Cassie, like our other casual canvas shoe, the Hana, is built for fun. We don’t recommend running ultra marathon in the Cassie, but high-performance FeelTrue® rubber sole, some of you will do more in the Cassie than just wearing yours for work, or hanging out, or a night on the town.

Hear from some women who’ve got their feet in the Cassie:

What you’ll love about the Cassie

It’s what makes all our Xero Shoes special — we believe in feet! Your feet are supposed to bend, flex, and feel the world. The Cassie lets you do that.

  • Natural FIT — the wide toe box lets your toes spread and relax. Plus the “XERO-drop” sole (non-elevated heel and low-to-the-ground) allows for proper posture, balance, and agility.
  • Natural FUNCTION — the flexible Cassie lets your feet bend, move, and flex the way that feet are supposed to. Plus, they’re so light, you might forget you have them on. A woman’s size 7 is only 6 ounces each.
  • Natural FEEL — the Cassie uses the 5.5mm FeelTrue® rubber sole. That means you get protection while still letting you feel the sensations that your feet want. If you need a bit of extra protection, just toss in the 2mm insole that comes with your pair.
  • Vegan-friendly materials — the Cassie has a canvas upper, with a cotton lining and microfiber accents. You can wash it with soap and water.
  • Huarache-inspired design — the heel/instep strap adds a subtle, eye-catching call out, but it’s also functional, holding your heel and cinching up around your instep.
  • Flexible heel — you can step on the heel and wear the Cassie as a slide

No, the Cassie is a canvas shoe, and will absorb any water it encounters. It is a light canvas, though, and should dry pretty fast after you take them off. Also, you can treat the Cassie with an aftermarket waterproofing spray… but that will make them a bit less flexible.

Though the Cassie is designed as a casual shoe, it’s certainly capable of much more than just hanging out. We’ve had people do all kinds of outrageous activities in them so far, but it’s up to your best judgment what you believe they are capable of handling. So, use your common sense and have fun

You can wash them with a mild soap and water mixture. The canvas is quite durable, and should come clean easily with a little scrubbing. DO NOT place your Cassies in the dryer when you are finished cleaning, let them air dry

While we designed the Cassie with a “Mary Jane” style that’s typically a women’s shoe, if you’re a man with a narrower foot (our women’s shoes are narrower than the men’s) and like this style… enjoy.

Shoe sizing, especially online, is not a perfect process. That’s why we have a free exchange policy.
We have sizing instructions at the bottom of the product description for the Cassie.

The Cassie fits “true-to-size” or a TINY bit small. So you’ll probably be okay selecting your “usual” shoe size. If you think you’re “between sizes,” go up a 1/2 size.

Also, the Cassie is wider than conventional shoes. Some people have experienced stretching in the canvas upper to slightly wider.

Keep in mind, though, that because the foot is three-dimensional, any two-dimensional measuring tool, such as a ruler or Brannock device®, can only approximate your true shoe size. Manufacturers model their shoes on different foot shapes, which is why you might be an 8 in one brand and a 9 in another.

We do! We’ve sold Xero Shoes to people in more than 85 countries around the world.
We use the US Postal service to send our shipments. The cost to ship will depend on the weight of the package and the delivery speed you select; several options will be provided at checkout.

All domestic shipments come with tracking. Limited tracking is available for some first class international shipments depending on the country, and full tracking is available with all Priority Express and Express International shipments.

Though almost all of our international orders arrive without incident, we strongly advise you to select Priority Express International or Express International if you live in a country with a less reliable postal service, including (but not limited to) India, Brazil, Mexico, South Africa, and Indonesia. We cannot guarantee delivery of packages shipped using First Class International.

International delivery can take anywhere from 3 days to 8 weeks depending on how long your order spends in customs at the border.

We advise you to know the import regulations of your country and understand that you will be responsible for payment of any duties and fees imposed by your government at the border.

All packages will be marked as merchandise; as a commercial shipper, we are not able to mark a package as a gift (if you’re giving Xero Shoes as a gift, that’s not the same as us sending a gift).

I’m crazy about the Cassie!

Just when you think Xero Shoes can’t get any better, they drop the Cassie! These shoes remind me of the classic Mary Jane shoes I used to rock in my teens and early 20’s, except way more comfortable! I love that there was no break-in period for these shoes. They were “adventure-ready” right out of the box! I’ve walked all over New York City in these with and without socks and my feet felt great all day-no blisters or achy feet at the end of the day. They have just the right amount of support to pad my feet from the hard city street but not so much that it buffers the feedback from the ground. I can feel how these shoes can really strengthen my feet! These are also great paired with a variety of outfits from dresses to skinny jeans! I even wear them to train my clients and always get a variety of compliments on them. Thank you Xero Shoes for always stepping up your minimalist shoe game!

I've loved xero shoes for a long time and am very excited to have an option I can dress up or down with. Really cute, really comfy, lightweight, and so fun to wear!

Such a comfy, everyday lifestyle shoe

I love wearing my Cassies. They have been a great everyday choice for me in the early post natal weeks (I've been wearing mine for the past month, since the birth of my daughter). They're versatile and look great with jeans or a skirt. I also love how I can just slip them on when I have my arms full and they're easy to do up with one hand! Most importantly, just like all xeros they're functional and they allow my feet to bend and flex freely.

Great

I got these for my mom and she loved them! She said she wasn't sure at first, but once she wore them she was hooked!
