Very Comfortable

As my first pair of barefoot shoes I wasn't sure what to expect.

I bought them to replace my flip flops as summer footwear for when I dont plan to walk far but need something on my feet. For this they are very comfortable and have completely replaced my flip flops. I have also started using them for doing weights and find they just feel more stable than my normal running shoes.

Overall I am very happy with them.

Comfortable and versatile

I'm very pleased with these shoes and have used them recently for a holiday in Porthmadog for walking in the sea and over rocks. The shoes dried out quickly and were comfortable without causing my feet to sweat. They are also fine for the gym and walking around town in the evenings. I also chose them for their environmental credentials and that fact they're Vegan friendly.


Bought some of these (well, three pairs now) for my daughter as she has grown but this is the first pair for me.

Mine, rather than Velcro are elastic laces, but still easy to get on and off.

Foot fits snugly but with toe room so my 11.5s are true to size.

Fine in the wet (paddling with the kids) without the spongy feel of my crocs which I’m very glad to retire. A lot more secure on my feet.

Obviously a thinner sole compared to crocs so you notice larger stones and as these are worn without socks I would not want to run far in them.

Overall, very happy with my purchase.
