Slushies belong in cups, not the insides of your shoes. Whether your Winters are rainy, bitterly cold, or the snow didn’t get the memo that it’s officially Spring, our waterproof Chelsea boots keep the elements out and the warmth in. 

From fall through the last throes of winter, these boots will be your trusty companions. Built on the same outsole as our beloved Primal Zen, you can expect the same zero-drop, lightweight, and ultra wide fit.

This boot can be dressed up or down, worn to the office, bar, or trail.  The Espresso colorway features a fully waterproof membrane and oiled leather upper so there’s no need to worry about the forecast. Just pull them on and go! 

Because of the oiled leather and waterproof membrane you will find that this upper is stiffer than the suede version, so if you're looking for a softer feeling right out of the box, then try the Chelsea Boot Cedar instead.

We recommend ordering UP 1/2 size from your normal US size. If you plan to wear a thicker sock, consider a full size up.

Unsure of your size? We recommend ordering 2+ pairs at a time, as we offer a flat shipping fee of $5.95 & free exchange options for US customers.

This shoe is available in only one width. It is built on our WIDEST Natural-Shape Last. (see image below)



With its waterproof membrane and full-grain oiled leather upper, this Chelsea Boot will keep your feet cozy and dry.


Places the forefoot and heel flat to the ground correcting posture, aligning your spine, and encouraging mid-foot strike.


Unlike traditional footwear that squeeze the toes together, our foot-shaped toe box allows for maximum room giving the toes ultimate freedom to wiggle and spread.


Our proprietary IBR outsole is what makes Lems incredibly lightweight and flexible - giving your foot the sense of weightlessness.

    Loving them

    I’ve been wanting these for a long time and they didn’t disappoint. I was hesitant about adjusting sizes but going up a half size as recommended was a perfect fit (usually and 8, got an 8.5). They’re versatile - I use them both to work and casually. Looking to get a pair in another color!

    Love them

    These are my go to boots for everything. I was sad to part with my old Boulder boots after 4 years of wear but these boots are so awesome I hardly miss the Boulder boots.

    My body has been waiting for these booties forever.

    I think these are my favorite pair of Lems shoes ever. Hands down, insanely comfortable - the footbed is perfect. Ridiculously attractive and cute shoes. I feel like I've been waitiing for this pair of shoes forever! I'm just so glad that Lems finally put out an attractive, black bootie that is slip-on. It's a dream come true.
