These are great! Had a pair of Dawgs which are similar, a knockoff of the Crocs. These are more comfortable. Being diabetic I like more room in the toes, etc. These provide that. Nice non slip tread just as advertised. There are no holes for ventilation so be prepared for some sweating. I take them off while at my desk to let my feet cool off and let the Crocs dry some. If you want something that is extremely light weight and comfortable to wear all day, Crocs are for you! BTW - you can flip the heel strap up and wear like a pair of clogs. I find it more comfortable that way.
