Designed for people with amphibious tendencies, this shoe is built to go the distances over land and sea.

  • Foot-shaped construction – for unrestricted foot freedom.
  • Sock-like neoprene ankle fit - to help keep little nasties out of you shoe and give full ankle mobility in and out of the water.
  • Water repellent mesh – for minimal wet weight.
  • Quick drain zones – to help pump the water out with each foot stride when you hit dry land.
  • Sticky orange rubber FG sole with low-profile lugs – for wet/dry rock grip and partner visibility when you're on the swim section.

Vivobarefoot has designed this shoe in collaboration with the original swimrun world championship partners at Ötillö Swimrun.

Great shoe, very comfortable

I love this shoe, I feel great walking in them every day. I'll definitely get another pair when this pair wears out.

Really love these shoes!

I bought these to try out as a new running shoe – and I live by a long beach, so bought the swim/run version.

First, I love wearing the shoe. It is so comfortable and I have walked miles in them already! I took the advice to phase in running gradually, and so have only done a couple of short runs and a couple of fitness classes in them.

I am still not sure whether I’ll be able to adapt my running style to use them as my main running shoe – a few issues with achilles and calf the first couple of times. However I’m going to persist and do it gently.

My overall rating is 4/5 rather than 5 only because of this slight question. However, I’m thrilled with the quality, feel and look of the shoe – and the 100 day try-out period gave me real peace of mind.
