Sizing & Fit

• Step oneHeel to the wall, stand on paper, mark the longest toe. Both feet, late in the day.
• Step twoAdd 10–12 mm to the longer measurement. That gap is toe splay, not slack.
• Step threeCompare with the insole length on the product page and take the size that covers it.

Measure Before You Order

Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe and measure from the wall to that mark. Do it late in the day — feet spread by a few millimetres over the course of one, and a shoe fitted at breakfast can feel short by evening.

Measure both feet. Nearly everyone has one longer than the other, and the shoe has to fit the longer one.

Add the Room, Then Pick the Size

Add roughly 10–12 mm to your longest measurement and compare that number with the insole length given on the product page. That gap is not slack: it is the space toes need to splay and the foot needs to lengthen when it takes your weight, which is the entire reason for a wide toe box.

Land between two sizes and the larger one is usually right, particularly in the trail line, where descents push the foot forward against the front of the shoe.

Where the Fit Should Feel Snug

Heel and midfoot. Toes stay free to spread; the back of the shoe should not lift as you walk. If your heel slides up and out, the shoe is too big however roomy the toes feel.

Socks Count

Thin toe socks add almost nothing. Thick wool socks can swallow most of a half size. Measure in what you actually intend to wear, and where that changes with the season, size for the thicker sock.

How the Collections Differ

Collection	Fit notes
Barefoot shoes	Widest toe box, zero drop, thin sole. Order to your measurement plus room.
Trail runners	Wide box with a more secure midfoot. Leave the full 12 mm for downhills.
Athletic sneakers	Closest to a conventional last. Between sizes, take the smaller one.
Slides & recovery	Generous by design. The foot should sit inside the footbed, not overhang it.
Sandals & flip flops	Straps do the holding. Match footbed length to your foot plus a few millimetres.

Coming From Cushioned Shoes

Expect the number to move. Feet that spent years in a narrow tapered shoe often measure wider than their owner assumes, and the first honest measurement is regularly a surprise. Trust the tape, not the size printed inside your old trainers.
