The Motus Strength II is the latest version of our pinnacle barefoot strength trainer, now with a new tongue construction for a secure, adaptable fit, plus a ribbed KPU overlay for full range of motion, enhanced flex and airflow. A supportive upper with durable, breathable mesh offers total protection and unmatched connection, while raised lugs provide grip and stability under heavy loads.
The Motus Strength II is engineered to withstand abrasion and protect during heavy‑duty training – from rope climbs and sled pushes to intervals and strength work like barbell lifts and kettlebell drills – all without losing barefoot feel. It’s durable enough for your toughest sessions yet light enough for dynamic drills – giving you the confidence to train your way, today and for a lifetime of wellbeing.

VEGAN**The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.
WEIGHT Based on a single shoe in Men's size: EU 42 | UK 8 | US 9 = 318g

FEET COME IN DIFFERENT SHAPES AND SIZES
Millions of years of evolution have done an amazing job. The human foot is perfectly designed for standing, walking, and running.
Remarkably, feet come in all sorts of shapes and sizes. Some have been compromised by a lifetime in conventional shoes, some naturally wider and some thinner and longer. We’re confident you’ll find a pair of Vivos to suit you.

FITTING
Measuring your feet will help tell us what your recommended fit is. However, some like a shorter, snug fit while others prefer a longer, more spacious fit. This is where personal choice comes in.
It’s also important to note there will be slight variations in size from one style to another. Please check the product page to check if a style runs large, small or true to size.
If you are still unsure about your size, visit our store for in-store measuring,
