VIVOBAREFOOT built the original Motus Strength as their first-ever shoe designed specifically for strength training and functional fitness – a sharp departure from the lifestyle and running focus of most of their catalog. That shoe won Best Minimalist Training Shoe at the 2024 Men’s Health Fitness Awards and Best Workout Shoes at the 2024 T3 Awards. The Motus Strength II is VIVOBAREFOOT 2026 refinement: same DNA, smarter details.
The core design philosophy is unchanged – a 2mm rubber outsole with 1.5mm raised lugs keeps you as close to the ground as possible during loaded movement, while a wide toe box lets the forefoot splay for natural balance under heavy loads. Zero heel-to-toe drop means your foot is in a neutral position through every squat, deadlift, and kettlebell swing.
What’s new in Version II?
New tongue construction
The most noticeable change is an engineered tongue redesign. A gusseted, more adaptive tongue that locks the midfoot down without creating pressure points across different arch heights – tongue no longer shift or fold on narrower feet during dynamic work.
Ribbed KPU overlay
VIVOBAREFOOT replaced the flat KPU overlay with a ribbed structure. The ribbed design creates flex channels that let the forefoot bend more freely during deep lunges and push-offs, while also opening up airflow paths that the previous flat overlay sealed off. The shoe reportedly runs noticeably cooler as a result – more breathable.
Improved forefoot volume
Version II added slightly more volume in the forefoot zone to reduce contact pressure in those positions, without widening the toe box itself. No hot spots on top of your forefoot during deep flexion moves – lunges, Turkish get-ups, rope climbs.
Outsole
The outsole is unchanged. The 2mm base with aggressive 1.5mm lugs and high midfoot sidewalls was already one of the grippiest barefoot soles on the market. VIVOBAREFOOT didn’t touch it – the right call.

Performance breakdown
Deadlifts, Squats, Barbell
This is the shoe’s core use case, and it delivers. The 3.5mm total profile (base + lugs) makes you feel genuinely grounded under the bar – closer to lifting in socks than anything else with this level of upper protection. The lug pattern provides excellent traction on both rubber gym floors and wooden platforms without the squeaking that plagues many non-lug barefoot trainers.
CrossFit, Functional Fitness
High midfoot sidewalls provide a degree of lateral structure that most barefoot shoes skip entirely. This matters on lateral shuffles, box step-overs, and any drill involving side-to-side direction changes. The ribbed KPU overlay also protects the upper during rope climbs – historically a death sentence for mesh-only barefoot shoes.
Kettlebell, Dynamic drills
The improved forefoot volume in version II pays dividends here. Deep swing positions, cleans, and floor work no longer create the forefoot bunching – shoe flexes with the foot rather than fighting it at the toe break.
Where It’s Less Ideal
It is not a running shoe. The structured upper and aggressive tread runs hot over long distances, and the outsole is tuned for grip over cushioning. For hybrid athletes who split time between the track and the rack, a separate pair makes sense – go with the VIVOBAREFOOT Primus Lite or Primus Road lines. Also, not ideal for casual daily wear – the silhouette reads “gym-specific” and the upper warmth becomes noticeable outside of training contexts.
Motus Strength II vs. Motus Flex
These two shoes occupy different positions within the Motus lineup. The Motus Strength II is the high-abrasion, heavy-lifting workhorse. The Motus Flex is a minimal, mobility-first trainer for calisthenics, primal movement, and bodyweight work.
| Feature | Motus Strength II | Motus Flex |
| Primary use | Heavy Lifting, CrossFit, Rope Climbs, Sled Work | Calisthenics, Yoga, Primal Movement, Bodyweight Training |
| Sole thickness | 2mm base | 2.5mm base (+0.5mm thicker) |
| Lug depth | 1.5mm raised lugs | 1.5mm lugs |
| Outsole construction | Single-piece, solid rubber – more rigid, better grip under load | Decoupled / split two-part sole – rolls into a ball, max flexibility |
| Upper type | Structured mesh + ribbed KPU overlay | Single-piece stretch-knit sock upper |
| Closure system | Traditional laces | Elastic toggle laces — slip on/off |
| Lateral support | High midfoot sidewalls | Minimal – flexibility is the priority |
| Durability / abrasion resistance | Higher – built for rope climbs and rough surfaces | Lower – lighter construction |
| Breathability | Good (improved in v2) | Excellent – knit upper is more open |
| Warmth / climate suitability | Can run warm in long sessions | Better for warm climates / gym environments |
| Lifestyle / street wear | Gym-specific silhouette | More versatile – cleaner look |
| Price (US) | $220 | $185 |
| Best for | Powerlifters, CrossFitters, athletes doing high-intensity loaded training | Mobility-focused athletes, yoga, handstand work, light cross-training |
Final Word
The VIVOBAREFOOT Motus Strength II is the strongest barefoot option on the market for serious gym training. VIVOBAREFOOT improved the fit and airflow where v1 fell short and left the outsole – the shoe’s defining feature – completely alone. At $220 it’s a premium investment, but the 100-day trial removes most of the risk. If you’re a lifter, crossfitter, or functional fitness athlete who wants genuine ground feel without sacrificing upper durability, this is the one to buy.

Frequently Asked Questions (FAQ)
Is the Motus Strength II good for deadlifts?
Yes – this is one of its strongest use cases. The 3.5mm total sole profile (base + lugs) keeps you close to the ground, the lug pattern grips rubber platforms without slipping, and the zero-drop stance lets the posterior chain load naturally.
Can I use it for running?
Not ideal. The structured upper runs warm and the outsole is tuned for grip over cushioning. For occasional short runs between sets, it’s fine, but dedicated running is better served by VIVOBAREFOOT Primus Lite or Primus Road lines.
How does it compare to Nike Metcon?
The Metcon offers slightly more cushioning and a more traditional heel cup but sits about 4mm higher off the ground and lacks the wide toe box. The Motus Strength II provides better sensory feedback and a more natural foot position for heavy lifting, at the cost of some impact protection on jumps.
Is it worth the price over the original Motus Strength?
If you’re a new buyer, yes – the v2 improvements are meaningful (tongue fit, forefoot comfort, airflow). If you own v1 and it still performs well, the upgrade isn’t urgent. The outsole – the most critical component for lifting – is unchanged.
Does Vivobarefoot offer a trial period?
Yes – VIVOBAREFOOT offers a 100-day trial on all orders. If the shoe doesn’t work for your feet or training style, you can return it within that window for a refund.
