MONO shoe (omnidirectional)

MONO a fore foot (ball) shoe hold between your toes

So first this isn't the shoe to walk for hours. It is when you have slippers at the door and annoyed that they always facing the wrong direction ( sure you also can leave them at 90° ) however like for sauna it just doesn't matter and you always can slip in right away. 

• Make sure to print them in TPU else it would be less comfortable and also more slippery.
• Ensure your foot ball is covered by the MONO else you will feel discomfort!
• Use Through version for wet or sand (loose ground)

Walking

You may think this can't work but when walking stairs or sprint you only use the ball of your feet and also people with high heels - so in general feet are designed that way, but for long walks or standing still it is more efficient to roll over the heel. But most animals are also just tiptoeing all the time (unguligrade).
