Great first barefoot shoe

Wanted these for a while and finally got my first pair. Ultra 3 Bloom were ideal for me as it was summer time when i purchased them which allowed my feet to breath and compete in mud runs as the water doesn't stay squelching in the shoe! Fit very well, plenty of room but not too big.

Feel very natural to wear and would recommend letting your feet get used to them so walking around for an hour or so a day then build up to let your feet adjust.

Only criticism is the colour wasn't as bright/clean as seen in the image but otherwise perfectly functional and delivered so fast!

Great pair of amphibious shoes

These are extremely comfortable amphibious shoes. Great for the garden, beach and in river. So run slightly larger in size so if buying again would go for a 5 instead of a 6. Love the eco-friendly packaging they come in. Also they algae based foam is very comfy and performs as you would expect.

The Feel of Nature

I have the Ultra III Bloom shoes for over a week now and I really like them. The shoe is very light and perfect for what I do outside. I love walking and swimming and this shoes if perfect for it. I'm not big fan of getting into lake/tarn without shoes because I don't like the pebbles and sharp rocks and I don;t need the hustle of changing shoes.

I'm always skeptical about wearing shoes without shock because sometimes the material can absorb the smell but these shoes don't.

At the weekend I had a few mile walk on trail in Lake District and they were really nice to walk in. It's so lovely to feel the smooth big rocks, small one can be tricky but then you learn how to put your feet down instead of stomping.

It takes a while to get use to the shoes but it's so worth it, I can not wait to get a different model of vivo shoes.
