Lems Shoes Waterproof Boulder Boot has long been our most requested shoe, and we’re confident that 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 change 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.

Great boots!

Hi. Great boots, wide, takes a while to get use putting on, great color. The sole is medium, as hardness go, no slippage yet. Recommend!

Thanks Florin!

Solid, Comfortable boot

Comfortable, fits slightly large as described. Good tread, looks good, includes a set of black shoe laces and black shoe laces w/ white flecking inside. Best website to purchase Lem's from in the EU price/selection wise as of Oct 2021.

Thanks Brogan - much appreciated!

Quick service but size chart is slightly questionable

Everything worked well and delivery in less than a week. The size chart, I measured as instructed and as the indicated size sounded just too big I went one half size down. It was still super big. I can still use them with big volumnious socks, but if tried them on, I would likely go one full size on if I could choose. The boots are super good and very comfortable... and light! Love them!

Thanks for the feedback and I'm happy about the fact you like the sizing.

Sizing is always personal and Lems recommends 16 mm of free space in front of you toes. Even that is too much for some. I also hop you used the cm field, not the insole cm length :)

Great service, excellent boots

I absolutely love my new boots. The size guide on the website was easy to understand and the boots fit perfectly. They were shipped super quickly and I was able to track them all the way from Finland to the UK. They arrived quickly and without issue. Would definitely recommend Urban Kit Supply.
