This rugged sandal is designed for real hardcore trails. Barefoot Ted has put the original Oso through rigorous testing on many trails including the Leadville Trail 100, where they performed exceptionally well.
Everything you need to feel secure and protected on the trail, with none of the extra weight or bulk. The ultimate minimalist trail sandal, featuring our grippiest Vibram tread, a super flexible sole with the utmost ground feel and and our patent pending Winged performance laces for an ultra adjustable, perfect fit.
Our patent pending Wing design allows for the simplest, most secure and intuitive LUNA experience yet! Wings keep your LUNAs securely in place without the use of a tech strap, while maintaining total lace adjustability and optimum comfort. Made of a flexible, smooth and very durable material, Wings are made to move with your foot and stand up to the gnarliest conditions.
Each pair of sandals are cut and assembled by hand for each order.
How does it compare to the other sandal models?
The Oso Flaco Wings comes with our secure and comfortable Performance 2 Winged laces. The Performance 2 winged laces include our LUNA Plug System, which consists of a soft, tubular nylon between the toes and a flat plug under the outsole for extended wear protection.
The remainder of the laces are made up of a 5/8" climbing-grade tubular nylon with an extra padded heel strap, making the sandals easy to slip on and off. The all new buckle at the top of the foot allows for simple adjustments thanks to the ability to tighten and loosen the buckle and slide the strap up and down the toe strap.
All sandals with the MGT footbed and Performance 2 laces will be made with vegan padding in the heel strap, making them entirely vegan!
**Note: The Performance 2 winged laces are not interchangeable with other laces at this time.**
ALL NEW WINGS MODELS DO NOT include the tech strap which is not required with the new wings attachment.
We stand by all products we offer at LUNA.
If you are not satisfied with one of our products or if they ever fail you, return them to us for a replacement, (partial or full) refund, store credit or repair.
A reasonable charge will be assessed for damage due to wear and tear or for repair.
For any production defect that you might encounter on your LUNAs, you have the MoonRock Guarantee. For example, your LUNAs should never delaminate on the sole or have its buckle or plug break during their lifetime unless they are purposefully abused.
Even though many LUNAtics put thousands of miles on their LUNAs, it is hard to give a definite lifetime. How a LUNA wears will vary from person to person, model to model depending on the intended use, gait, weight, load, terrain, running form, and climate.
These would void your MoonRock Lifetime Guarantee: Intentional misuse. Returns on products which show normal wear and tear but no defect. Any damage incurred from improper cleaning or self repairs (e.g. cutting or removing tags, cutting the soles of your sandals).
