LUNA Oso

Size Guide

  • Made in Seattle 

    The LUNA Oso with the non-slip MGT footbed with our super secure traillaces with tech straps is one of our recommended trail running adventure sandals. 

    The LUNA Oso [oh so] (Bear in Spanish) is a durable, premium trail sandal with a tough, rugged sole and protective midsole, topped by non-slip MGT footbed. An aggressive tread pattern makes the Oso a great option for off-road running and adverse weather conditions where maintaining your footing is essential. This sandal can handle most advanced trails and wet conditions, whether running or walking.

    The LUNA Tech Straps started with the Oso, but is now available separately for any LUNA model click here. If you need more strapped-down security for technical trails, mud/obstacle runs, MovNat adventures, wilderness walkabouts, Fuego y Agua Ultra-ing... this strapping system was developed with you in mind.

    The Oso Necessities: 
    Weight: 7 oz (per sandal, laces included, size 9) 
    Thickness: 11mm 
    Footbed: MGT

    How does it compare to the other LUNA models? 
    • The LUNA Venado is our lightest, thinnest (7mm) model. Great for road running or casual wear, and molds well to your feet. 
    • The LUNA Mono [moe no] is our most versatile sandal. It's fairly thick (12mm), but also light weight and molds to your foot quickly. It has some traction for trail running. 
    • The LUNA Oso (11mm) is secure and rugged, but also our heaviest, least moldable option. If you need a tough, long-lasting LUNA for rocky terrain or a trail ultra marathon, the Oso is for you. If not, no Oso for you, yo! 
    • The Leadville Trail (11mm) and Leadville Pacer (9mm) are lightweight, moldable trail alternatives to the more protective Oso. They have more aggressive tread than the Venado and Mono, making them better for trails. The aggressive tread will wear out quickly on pavement though, so stick to trails with these sandals!

     

    MGT FOOTBED

    The Oso comes with our MGT (Monkey Grip Technology) footbed, maintaining the black, low profile, look of the naked top LUNAs while improving traction and durability. For wet and muddy conditions, the MGT footbed is king.

     

    TRAIL LACES

    The Oso comes with a modified version of our secure and comfortable ATS (All Terrain Strapping) laces. The ATS laces include our Luna Plug System, which consists of a soft, tubular nylon between the toes and a flat military spec nylon plug under the outsole for extended wear protection.

    The Trail Lace Variation: 
    The buckle and basic design remain the same, but the elasticized heel strap has been replaced by a non-stretch, cushioned heel pad to add more security and comfort to the overall strapping system.

    Tech Straps: 

    LUNA Tech Straps are patent pending add-on ankle straps that helps keep your heel straps and ankle secure. It's the final piece of an ultra-secure puzzle meant to keep your foot in place on slippery, hilly, and otherwise technical terrain.

Hey LUNA Monkeys, I don't fit into any of you standard sizes, what can I do?
No problem. We have experience making "special" sandals for people just like you. Is your foot too narrow?
Is your right foot significantly longer than your left? Are your toes longer or shorter than average? We can help.
There are a few steps to getting a non-standard or custom LUNA made.
Firstly, we need to determine if your feet will fit any of our standard sizes. If you've printed out our templates and found none fitting you, then a custom LUNA is the best option for you, contact us at support@lunasandals.com or call call us at 855-586-2726. We can help.
