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 patented Performance Laces & Tech Strap for an ultra adjustable, perfect fit.
How does it compare to the other sandal models?
The Oso Flaco RETRO comes with our secure and comfortable Performance 2 laces. The Performance 2 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 laces are not interchangeable with other laces at this time.**
ALL NEW RETRO MODELS include the tech strap which is the greatest way to keep your sandal in contact with your feet in mud, it also prevents the heel pad from falling off your heel bone.
