I got these as a present. I live in the caribbean - temp is 33 celsius all year round.

I've used these to hike through a river with a stony/rocky bed, swam along in the river as well - the hike lasted about 4 hours (inclusive of hanging out along the river, swimming, walking/hiking in the river as well as along the rocky/stoney shore.

I did another hike along a river same stoney/rocky bed but with some trails.

I also did a hike through a jungle (thick trail), ants ridden, slightly slippery, uphill (almost climbing - had to hold on and grip with my feet at some parts), along a river bed, along a sharp ocean rocks, along the beach --- about 6 hours altogether. This is to give you an idea of the terrain these shoes can handle.

I had no idea they would hold up so well. The above are decent hikes and these shoes which are not meant for such tough usage have survived and performed superbly. My feet never got poked from the sharp rocks, yes with this usage sand got in but it was easily washed out and I slipped the shoe back on and was off. I hiked through an ants patch ... which was more like the trail for about 25 metres was filled with ants. The ants did not get into the shoe but as expected I got a few bites but with the quickened pace through the trail - the shoes held up, kept their grip and allowed for agile movement.

I have a bad back, a dodgy knee and other things - after such extended use on each hike - I suffered no pain in my feet and no pain felt in my back etc. I don't know why - this is just my experience with this brand.

I highly recommend this shoe - yes after the third hike the soles of the shoes began to bunch up but it didn't bother me much - I am pleased with these shoes and would recommend them. Well done to the manufacturers I can't believe how great these shoes perform!
