Made for punishment.

There are flashier, fancier trail shoes than the Fizik women's M6B Donna Boa Shoes. But who cares? When it comes to recreational hammering or punishing spin class intervals, the M6B Donna's carbon-reinforced rubber outsole and Boa/hook-and-loop strap closure system are more than equal to all but the pro-iest efforts.

  • A trail shoe that does double duty at spin class
  • Carbon-reinforced midsole for efficient mashing
  • Secure wire dial closure for all-day comfort
  • Reinforced Microtex upper enjoys anti-rock durability
  • On-trend colors complement fitness attire and Lycra alike

  • Familiarity: I've used it several times

As others have said, these shoes do run narrow! I took these on a long desert biking trip, and was unable to keep them on the entire day. I am hoping they might loosen up after a bit of wear, because they are super cute and comfortable everywhere else.

Gorgeous Shoe, Runs Very Narrow

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: 39

I really wanted these shoes to work for me. Style wise they are super fun, with matte black body, black patent trim, and both hot pink and turquoise velcro straps. They are really well made shoes that also look great on. (I've never been able to say this about a bike shoe before!) Unfortunately, they fit like "straights" and run narrow, meaning the heel feels about the same width as the front of the shoe. I wear a women's size 8 M street shoe, and purchased the size 39, which were plenty long enough. My heels slipped out the back, and in trying to tighten the straps enough to keep my heels in, they became too tight across the balls of the foot, and put my feet to sleep. In trying to loosen them up across the ball of the foot, my heels slipped out the back. There is no way to adjust them for narrow heels, with a slightly wider ball of foot (German shaped foot). Bummer for me, they didn't fit right, and I had to return them. They are still a gorgeous shoe! Side note, they do not come with plugs for the bottoms, so if you aren't planning to put cleats on them, they won't work for you.

Unfortunately had to return...

I loved these shoes....great colors, and extremely comfortable. Unfortunately when we tried them at the bike shop with our pedals I couldn't clip in, and the guy was going to have to shave down some of the sole to help me do so. I decided to go with a different pair that clipped in easily and returned these.

These are super comfortable to ride in right out of the box, and are easy to walk in. The boa system is convenient and easy to use, and the colors are awesome!

Snazzy and comfy!

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: 40

I haven't rode in these shoes yet, but I liked them so much out of the box that I wanted to share my initial impressions, (I'll update my review once I put some miles on them.)

Initial impressions:

* I love the boa system

*They're very comfy right out of the box

*They are sooo cute, and have lots of flair with the teal and hot pink Velcro accents

*The reflective black piping/accents are not only super ample, but nice and covert. (These are my new commuter shoes so I'm VERY stoked on the amount of reflectivity they have!)

I've got wide, flat feet and these seem to be plenty roomy for my feet. Seem to run true to size, (I'm a solid size 40.)

Can't wait to rock these!!!
