Product Description

When the weather turns cold, but you still want the comfort, benefits, and sheer fun of barefoot-inspired, natural movement, the Mika is for you.

This stylish minimalist boot has 3 cold-weather foes:

  • Water-repellant canvas
  • Cozy flannel lining and stylish 70/30 poly/wool blend collar
  • A heat-reflecting warming insole

And at only 12 ounces each for a women’s 7, you might stroll your way through the entire winter and forget you even have them on.

The other reasons you’ll love the Mika are its true Xero Shoes heritage:

  • A wide toe box — lets your toes spread, splay and move naturally
  • Low-to-the-ground design for balance and agility
  • Non-elevated, “zero-drop” heel for proper posture
  • The flexible sole lets your feet bend and move the way they’re supposed to
  • High-traction FeelTrue® rubber sole with dual-chevron tread for traction, backed by our 5,000 mile sole warranty
  • Lightweight construction for “barely there” comfort

Tackle the cold in style in your new Mika and Live Life Feet First!

Light and comfy

Love these, they’re light as can be, super comfy, and so far they’re warm, can’t wait to see how they are when it's really cold and icy but so far, super happy with them!

Bought a size7 w/zipper. You might consider a full size bigger?

I got a half size bigger as is suggest in size description. Boot as described does run small! I would go a full size larger than your normal if you need wear thick warm socks. I am short and have small/slender feet and wear between 6-6.5 depending on brand. When I first put boot on with a semi-thick pair of Smartwool socks, I had no wiggle room for my toes. I put on thinner socks. This was a bit better but not much toe splay.... So I then took out the warming lining cushion to make more room and this is when it fit the best. Not exactly ideal but I test walked hem and was happy with the feel. being petite, this size fit well around my calf & small ankle frame, so I'm staying with the smaller boot. Fingers crossed they keep my feet warm w/out bottom liner as it gets colder here in Seattle. On my first dog wearing without liner they were still very comfortable so I'm happy.

Nice boot

They’re comfortable but need more cushion for our cold winters. A big big for my feet. A half size smaller would have been better.

Love these boots

I really like the style of these boots and they keep my feet warm. I would recommend getting one size up from your usual shoe size. I sized up and it worked great for when I wear thick socks. Awesome boots!

Mika boots

These boots are 1 of 4 shoes I brought from Xero this summer. I absolutely love all of them. With the old shoes I had, my feet would always hurt for a few minutes after taking them off and I would hear the muscles pop as I flexed my feet. However, that didn't happen with Xero. Once I walked about 10 miles on a sunny Saturday around my local town that has lots of hills wearing Mika boots. My feet didn't hurt that night, but my ankles were super sore until the next morning. Overall, these are surprisingly comfy. The only weird thing I am still getting used to is the difference in my height.

Magical!

I hike about 30 miles per week in the Colorado mountains where I have lived for 49 years. I buy new hiking boots every year because I wear them out. The Xero Mica is the most comfortable hiking boot I have ever worn. I actually bought a second pair. It moves with your feet. The thinner soles surprised me! Super grippy on steep craggy climbs. Super quiet if you like seeing animals. Less cumbersome, more precise footing. Zippy! I find I’m able to enjoy the scenery more because my feet can feel what is going on underneath so I don’t need to pay as much attention to the ground. Thank you for making these shoes!!!

Loved the insulation and the zipper! They so get pretty wet when exposed to rain/muddy terrain. Love them around town though!

WALKING ON AIR

I've been a diabetic for 59 years. My feet have become extremely sensitive to seams and even tiny defects inside shoes. Plus, I need inner soles that are especially supportive and soft. These boots fit each of my requirements perfectly. I have never owned more comfortable boots.
