The Ultra III is our amphibious shoe perfect for adventures on land and sea. The great-great grandson of the original Ultra, launched 7 years ago, has been redesigned to be lighter, stickier, more barefoot than ever. The lightweight hexagon upper design is breathable, non-absorbent and drains water easily. The new hex grip outsole made with sticky rubber gives you all that good underfoot feeling, flexibility and incredible wet and dry traction.

We're confident that after experiencing the joys of natural foot freedom, your feet won't want to go back to 'normal' shoes.

So confident, we've introduced a 100 day trial to all orders. If you change your mind within that period, we're happy for you to return your shoes for a full refund with no hassle.

Your trial will commence automatically from the date your order arrives. Simply check out with your shoes as usual and we'll take care of the rest. (Standard Ts and Cs apply).


Ultra III is inspired by the lightest and strongest shape found in nature, the hexagon EVA structure lets your feet breath and drains water easily. Lightweight like a running spike and grips likes a climbing shoe.

  • Elastic lace and toggle – for quick and easy adjustment
  • Sticky rubber sole – for grip in and out of the water
  • Honeycomb EVA upper – designed to mimic nature’s most perfect shape for the best fit
  • Vegan

Ultra III Men's

I love these shoes! i'm a size 13 and purchased a 12.5 because they run a bit larger, and they fit perfectly! I love the minimalist design and look forward to more exciting designs.

Great All Purpose Shoe

Got my kids these before so now it's my turn. I like them over all. The inside's grippy, works well with bare feet. They're structured enough that I could get away with putting some socks on and wearing them in normal casual situations, you can't see very much through the gaps. There is a bit of pressure on only the left shoe where it creases in front and touches the top of my foot but I think it'll go away as they wear in.
