We create our footwear using lasts based on real feet. Because of this we make it easy to find your perfect fit. 

1st. Step onto a piece of paper and with a pen mark just behind your heel and in front of your longest toe.

2nd. Do this for both feet and then measure the centimeters between these lines. This measurement is your Mondopoint.

3rd. Using the measurement from your longest foot find your correlating size below.

Best Boots Ever

Have only had them a few weeks, and no big hikes yet, but most comfortable boots out of the box that I have ever purchased!

Love them, Recommended them

Owned 6 months. Use them daily 2-3 times a day on my dog walks. Lots of mud, water, concrete, trails, you name it. Have also used them on hikes. Had Vasque (some low end hikers) and OBO in the past. Like these much more.

Very comfortable from day one and getting more comfortable. Very waterproof as I've been ankle high in water without getting wet. Walking on wet rocks and the grip is better than any shoe I've owned (see above). THey have a great sole design. These are supportive for what I've put them through, but I haven't done backpacking or the like. These are heavier than the above mentioned boots, but not excessively so. With that you get an assurance in every step, that I didn't feel before. Again, without model numbers, this may be a bit of apples to orange comparison. YMMV

I'm just hoping that the tread lasts. I can't say one way or the other at this point. Told my spouse to buy a pair and she just put in the order today.

Really love them

They’re great. Super comfortable and capable.
