after breaking shoes in, they are very comfortable. however, i find the venting doesn't necessarily help to keep feet cool in a very hot climate (it is almost more cool/comfortable to wear socks with these shoes).. and once the shoes are wet, they stay wet for a long period of time. they aren't bad shoes, but if faced with similar hiking/trekking situations to the ones i bought these tevas for, i wouldn't buy these shoes again.
