Lems Shoes Size Chart

You should measure the length of your feet first - Lems has provided instruction video and guide to measure your feet correctly. You can find the complete sizing guide here.

After you have the measurement refer to "Foot length cm" against the longer foot. Then pick the matching US size. All US sizes are Mens US for technical reasons. Womens US size is always size + 1.5 if you need to know it.

Recommendation is to leave 1-1.3 cm space for movement (sizing charts account for this). If you need additional room in the shoe, you can remove the insole for extra volume.

Marcin S. (Pomerania, Poland)

Super comfortable and stylish boot.

Thanks Marcin!

Trond A.Ø. (Oslo County, Norway)
Great boots, expensive customs handling fee

The boots are roomier than groundies with a somewhat thicker and softer sole so comfy for new barefoot walkers or standing at work. The leather is supple but not as thick as this type of boots usually are. Super comfy My new winter boots!

Thanks Trond Are! Happy you like the shoes, the shipping fees are exactly what we pay for them - it is high, but we can't do anything about it.

Rene T.
Very good..

Shoes. They look very good and are super confortable. For the winter /cold season it doesn't matter to me if the sole is thicker than real barefoot shoes. The sizing of lems seems to be pretty accurate for me so just measure the foot.

Thanks Rene!

Laurynas (Siauliai, Lithuania)
Best boots ever

I recently switched to barefoot shoes and Lems are by far the best for casual use.

Thanks Laurynas!

Anna S.
Täydelliset kengät

Pehmeät, kevyet, ihanat jalassa. Ulkonäöllisestikin aivan täydelliset. Koosta valitsin suositusta pykälää pienemmän ja kengissä edelleen hyvin reilu villasukkavara.

Kiitos Anna!
