I bought this shoe for my trip to the Big Island of Hawaii. I'm so glad I did because the terrain was treacherous. Lava rock EVERYWHERE. Going from kayak, to snorkeling, to hiking, was easy with this shoe and I was the only one on this trip who didnt get chopped up coming out of the water or on our hikes.
The best and worst part was hiking 3 miles in the dark to watch the lava. It was pitch black over rocky unstable terrain and at times when we got a little off track we were actually sinking into the molten lava. All you have to do is put a good sock on with this shoe and you are protected. I had one shoe for every activity. I should never have taken them off because when I did I ended up leaving them at the Volcanoes National park when I changed into my $10 flip flops.
They are worth the money for sure and when I save up I WILL buy another pair.
