These shoes are perfect to wear in hot climates or when walking/hiking a lot.  First pair I bought to go out west on vacation in May - lots of hiking. I have other Keen shoes for water that have open areas that I wear everywhere for the comfort factor (heat/support), so I bought this Keen style to keep out the small rocks, etc. while hiking.  They did not fail me.  No blisters, very light weight & breathable.  If you have trouble wearing the heavy, hot hiking boots like me, then this may be an alternative for you.  I also have a wide ball and narrow heel & Keen shoes keep my ankles/heels secure. I didn't carry a heavy pack hiking at Grand Canyon, Canyon DeChelly or Yosemite, so cannot comment on how they hold up under significant weight for long periods of hiking.  But I did carry a light day pack (~10 pounds) and my feet were fine. I wear thin DeFeet socks with these shoes as with all my sports shoes. I just recently bought this second pair as a back up for a better price here on Amazon.
