Tubular Softness

Have you ever noticed how soft your LUNA laces were? We obsess on that stuff and look for the best combination of softness and durability. We are always looking for ways to source the highest quality materials available. Innovations in material combinations have lead to old time favorites.

For those who demand the best in class performance focused minimalist footwear that can handle the BIG adventures, the Oso Flaco is super attractive.

Using our specially developed Vibram Megagrip studded tread, we've built a sandal that can handle the complex world of real adventure: mountains, rivers, trails, mud.


Most men tend to size down 1/2 to a full size with LUNAs.
