  • A Minimalist Boot for the Outdoors & Around Town

    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.

    Water-Resistant, Lightweight, Wide Toe Box

    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.

    Works Great With Other Natural Footgear

    This boot also works well in combination with Injinji toe socks and Strutz Pro or Pedag metatarsal pads. The Lems Boulder Boot works well in temperatures as low as 15 degrees F (about -10 degrees C) when used with an appropriate sock. Each Boulder Boot weighs about 9.9 oz.

    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.

    Tip 1: To create additional roominess within the boot, please consider removing the included (optional) boot liner/footbed; 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, please consider sizing up, especially if you are on the border between sizes.
