PickGuideSaguaro Ground Review: Men's Ultra-Thin 2.8mm Barefoot Training Shoes at $87.99
Most barefoot shoes compromise: they keep some cushioning, some heel lift, some buffer between your foot and the ground. The Saguaro Ground doesn't. With a 2.8mm natural rubber sole and a second-skin 18-gauge knit upper, it's built for the barefoot purist who has already made the transition and wants as little shoe as possible.
The Saguaro Ground is the brand's most minimal adult shoe — a five-toe barefoot trainer designed for those who have already adapted to minimalist footwear and want to go further. The defining spec is the sole: at just 2.8mm of natural rubber, it's thin enough to feel individual textures underfoot while still providing grip and basic protection on gym floors, light trails, and indoor surfaces. The upper is 18-gauge knit fabric — described by Saguaro as a second-skin feel — that wraps each toe individually and follows the contour of the foot without structure or stiffness. The insole is a 4mm recyclable polyurethane foam that can be removed. The result is a shoe that weighs almost nothing, flexes completely in every direction, and gives the foot the kind of proprioceptive feedback that cushioned trainers eliminate by design. Not waterproof but quick-drying; hand-clean only; zero drop from heel to toe. Available in Black in EU sizes 39–44.
Pros
- 2.8mm natural rubber sole delivers true barefoot ground feel — thinner than most minimalist shoes on the market
- Five-toe construction lets each toe splay and move independently, not just a wide toe box
- 18-gauge knit second-skin upper wraps without bunching or hotspots
- Zero drop platform — heel and forefoot at identical height for natural posture
- Natural rubber outsole is grippy on gym floors and light outdoor surfaces
- 4mm removable insole — can be used with or without for more/less ground feel
Cons
- 2.8mm sole offers minimal protection from sharp objects — not for trail running or rough terrain
- Five-toe design requires adjustment period if you've only worn standard toe boxes
- Black only — no color variants available
- Hand-clean only — no machine washing
- Not waterproof — quick-drying, but wet environments are not its element
Who It's For
Good For
- Barefoot shoe veterans who have completed the transition and want maximum ground feel
- Gym and indoor training — weightlifting, cross-training, yoga, mobility work
- Five-finger shoe fans looking for a more shoe-like aesthetic than classic split-toe designs
- Runners looking for a training flat that builds foot strength without traditional cushioning
Skip If
- You are new to barefoot shoes — the 2.8mm sole requires prior adaptation
- You need a shoe for rocky trails, wet terrain, or long-distance road running
- You want color options beyond black

Frequently Asked Questions
Is the Ground suitable for beginners to barefoot shoes?
No — Saguaro specifically notes this shoe is for those who have already adapted to minimalist footwear. The 2.8mm sole provides almost no cushioning buffer. New barefoot shoe wearers should start with a thicker-soled model and transition over several months.
What activities is it designed for?
Indoor training, gym sessions (weightlifting, cross-training, yoga), and light outdoor runs on smooth surfaces. Not recommended for trail running, rocky terrain, or prolonged wet conditions.
Can the insole be removed?
Yes. The 4mm polyurethane foam insole is removable, allowing you to run the shoe fully sockless and reduce total sole stack even further.
How does it compare to traditional five-finger shoes like Vibram FiveFingers?
The Ground looks more like a conventional trainer from the outside — the five-toe construction is visible but the knit upper gives it a sleeker appearance than classic split-toe models. Ground feel is comparable to the FiveFingers category.
Is it machine washable?
No. Hand-clean only: soft brush to remove loose dirt, gentle scrub with mild detergent and warm water, wipe down with damp cloth, air dry at room temperature.
Verdict
The Saguaro Ground is exactly what it says — a shoe engineered to keep you connected to the ground with as little interference as possible. The 2.8mm sole and five-toe construction are genuinely extreme by mainstream standards, and that's the point. If you've put in the months to adapt your feet to minimal footwear, the Ground delivers the most authentic barefoot-in-a-shoe experience in the Saguaro lineup. At $87.99, it's priced fairly for what it is.
