Ultra III Bloom Mens - Obsidian

The Ultra III is a vegan outdoor shoe that is versatile enough to tackle land or sea, and lightweight enough to take almost anywhere.

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).



Following the launch of the Algae Green Ultra Bloom, we're introducing a new colourway this season.

The Ultra Bloom is a lightweight and breathable closed-toe style, designed to be the ultimate adventure shoe for use on land or sea.

Great, breathable shoes

I bought these shoes for working shifts at the hospital. What initially attracted me was the prospect of having a shoe that would breathe, and also had a barefoot sole. And so far I've really enjoyed using them. My feet are comfortable after 8 hour shifts where I walk and stand a lot.
I've no experience with using them as amphibious shoes, so if you're looking to buy the shoes for that purpose, you should look for another review ;-)
I've had to go 1-2 sizes down. I usually use size 43-44, but I had to return a size 43 for a size 42. Keep that in mind if you're a first time purchaser.

I like it

Super nice and comfortable.
