Lems Boulder Boot Black
A Closer Look
From Our Customers
“I can finally run and walk with very little (if any) bunion pain. I bought the Lems Boulder Boot this summer and trekked 25 miles over two days with NO bunion pain. I put them side by side with my traditional hiking shoes and was appalled [...] THANK YOU!”
—R.W., Berkeley, CA
“The Lems Boulder Boots just arrived and they are wonderful. They feel so good, I don't want to take them off! Tried them out on the gravel driveway, which I go up and down on foot many times each day. Perfect! I love them! Thanks for the info and helpful products for making my feet with bunions feel great. And my knees, too! In gratitude and appreciation.”
—J.L., Leicester, NC
“I love these boots! And with Correct Toes, [they are] all the more satisfying. They really offer everything I want: healthy feet, very light, wonderful sense of the terrain upon which I am walking while plenty of protection from sharp protuberances, and the height offers protection from abrasions of the ankles.”
—J.F., Boulder, CO
“I just opened my mail on Saturday to find my Boulder Boots. I LOVE them. The fit is very nice and after just a few jaunts [...] I can tell they will be allowing my foot to return to normal. Thank you!”
—C.D., Ovid, MI

A Foot-Healthy Minimalist Hiking Boot
The Boulder Boot is a minimalist boot that supports natural foot health. This versatile and lightweight boot is flat from heel to toe, possesses a toe box that is widest at the ends of your toes, and is completely collapsible—the perfect footwear for trekking or other outdoor activities, or for around town.
Wide Toe Box, Compatible with Correct Toes
The Boulder Boot’s upper is made of 100% water-resistant nylon to help keep moisture away from your feet. The boot’s generous toe box is compatible with Correct Toes and allows you to experience the comfort and foot health benefits that come with natural toe splay. This barely-there, vegan boot contains no heel counter, toe counter, or shank, and it packs away easily, preserving space in your travel bag or luggage.

Note: Sizing varies between brands and sometimes even between different models of the same brand. What follows is the sizing information specific to the Lems Boulder Boot:
Women's US Sizes Women's UK Sizes Women's Boulder Boot Sizes 5.5-6 3.5 - 4 37 6.5 4.5 38 7 - 7.5 5 - 5.5 39 8 - 8.5 6 - 6.5 40 9 7 41 9.5 7.5 42 10 - 10.5 8 - 8.5 43 11 - 11.5 9 - 9.5 44 12 10 45
If you're still unsure of what size to order, consider ordering both sizes and then simply return the size that doesn't fit as well for a refund. If you have concerns about sizing, feel free to contact us or Lems customer service. You can also use this Lems Boulder Boot Sizing Guide to help you determine the best possible size for you.
Tip 1: To create additional roominess within the boot, we suggest removing the included (optional) boot liner/insole; this action does not, in any way, affect the performance of the boot.
Tip 2: Correct Toes toe spacers will often add width and length to the foot. If you’re planning to wear Correct Toes with your footwear, we recommend sizing up, especially if you are on the border between sizes.
