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.

Lems Shoes Waterproof Boulder Boot has long been our most requested shoe, and we’re confident they’ll be worth the wait. Speaking of weight, this boot still maintains the lightweight frame you’ve come to know and love from Lems — even though we’ve added a unique waterproof membrane, these puppies will still hit the scale at a featherlight 366 grams (12.9oz).

The overall construction has also changed, and everything has been reinforced; from a thicker gauge thread to an overall stronger outer construction, this is our toughest pair yet. And yes, before you ask, they’re zero-drop.

This kind-of-a-big-deal boot also utilizes a pre-treated leather upper that can be reapplied with waterproofing wax/spray to help extend its water repellency. Lems Shoes recommends using Otter Wax Boot Wax with their shoes.

All Lems Shoes are unisex so that the same model will fit men and women. Please check the size chart before ordering - Lems also changed the sizing charts in late 2019 by adding new sizes.

Kiitos - thank you!

jarno h. (Uusimaa, Finland)

Nopea toimitus, menin kokotaulukon ohjeistuksen mukaan ja kengät istuu täydellisesti jalkaan.

Kiitos Jarno!

Lari L. (Uusimaa, Finland)
Super mukavat, tyylikkäät ja kestävät!

Aivan ylivoimaisen hyvät kengät. Laadukkaasti valmistettu. Todella mukavat jalassa kun on tilaa, nahka joustaa ja pohja on juuri mukavan pehmeä. Vedenkestävyys myös huippuluokkaa kun säännöllisesti sipaisee mehiläisvahapohjaista kengänhoitovahaa.

Kiitos Lari!
