The Functional Footwear design concept is based on the principle of toefreedom®, which provides the runner with an increase in stability due to extra room for the big toe to anchor, stabilize and control the foot. The rest of the body can relax, move efficiently and avoid overuse and unnatural stresses on joints and muscles.
In conventional footwear, the toes (especially the big toe) are squished and cannot perform their natural function to anchor and stabilize the foot. As a result you stand, walk and run on an unstable base which leads not only to discomfort but is also the most common denominator for pain and injury.

We at Joe Nimble believe, that a tree is only as strong as its roots; just as the roots of a tree adapt to the shape of a container, the shape of the foot adapts to the shoes you are wearing. Conventional shoes with a shoe-shaped toebox create unnatural, shoe-shaped feet. From the assessment of thousands of feet worldwide, we have learned that just as weak and twisted tree roots affect the stability of the trunk and branches above, so do weak and twisted toes affect the stability of the runner above.

Common injuries in trail running like knee-, metatarsal- and lower back-pain are due to a lack of skill in switching between gears. The combined benefits of the toefreedom® concept and the flexitec insole have never been offered before in a trail running shoe and we believe this unique combination can be an essential part of the solution to pain-free trail running.

BIOMECHANIST, RUNNING COACH AND CREATOR OF THE FUNCTIONAL FOOTMAP.
Lee is one of the most recognised coaches for running technique on an international level.
His knowledge and experience in running biomechanics and foot function has benefited injured runners, both recreational and elite around the globe and led him to develop the Functional FootMap assessment system.

The 4mm thin spring-steel insole is modelled on the anatomy of the foot. Its unique construction promotes an even weight and pressure distribution throughout the foot and ads an extra layer of protection from sharp, irregular objects on the trail. Experience a new level of confidence and performance during your run, after inserting this simple but brilliant piece of innovation.


SHOE PIONEER AND INVENTOR OF THE FUNCTIONAL FOOTWEAR DESIGN CONCEPT
Sebastian´s family has been making shoes with toefreedom® for over three decades. His experience of helping people all around the world to improve their foot function through the benefits of toefreedom® and his passion for running has led him to create the Functional Footwear Design Concept.

Michelin has been forging a better way forward for over 100 years. They have spanned millions of miles on the mission to develop groundbreaking multi-surface contact for vehicles operating in the most challenging environments all over the world. We decided to partner with Soles by Michelin because of their unrivalled expertise in rubber and tread design to equip our nimbleToes Trail Addict with the perfect outsole for Functional Footwear to meet the unique demands of trailrunning.

When crewing at the worlds toughest footrace, the Badwater Ultramarathon, a few years ago, Sebastian observed that a lot of the elite athletes cut open the front of their running shoe to have more freedom for their toes and reduce the risk of injury. His unique know-how in making casual shoes with toefreedom® inspired him to introduce this design philosophy to the running shoe industry.

noun
an activity that is natural to or the purpose of a person or thing. (Oxford English Dictionary)
The purpose of the foot is to provide a stable base of support to control the direction of the body weight during the stance phase of locomotion [1-3]. Newtonian physics dictates that a wider base of support is more stable than a narrow base. Width and stability of the forefoot is crucial in this regard as the highest forces during mid stance occur at the forefoot [4, 5]. A greater spread of the toes, the great toe in particular, reduces forefoot peak pressures, distributes force more evenly, and stabilises the foot and ankle [6-8]. Toes squashed together by years of wearing narrow shoes that do not respect the natural fan shape of the human foot [9] are common [10] and are linked to instability and movement-related pain [11, 12]. Natural function can be restored by regular loading of the feet in footwear that respect natural design of the foot [13] and permit freedom for the toes to spread and stabilise the foot.
Pain-free movement begins with a stable base of support. A stable foot requires Toe freedom, only functional footwear provides toe freedom. Joe Nimble ‘functional footwear’ is based on this science.

DR WILKINSON
Dr Wilkinson´s research area is the biology of human health and performance. His work has included the biomechanics and performance determinants of distance running and the link between plantar sensation and regulation of bipedal gait. He has a particular interest in the influence of footwear on foot structure, function and joint loading during running.

If you’re new to Joe Nimble Functional Footwear you might be wondering what the right shoe size is you should buy. Well, the good news is: You just need to order your regular shoe size.
MEASURE YOUR FEET
If you are not sure about your right shoe size, here are some simple instructions for measuring your feet. You only need:
This is how it works: Stand on the paper with both feet while you are wearing socks. Simply trace around the outline of your feet with a pencil one after the other.
Important: Always hold the pencil upright on the paper, not leaning tot he inside or outside in order to get an accurate result.
Now simply measure the length of your drawing. Measure from the tip oft he longest toe tot he bottom (at the center) of your heel. If your feet are different sizes, then the bigger foot determines the correct shoe size.
