I made a mistake ordering this particular boot as I misread the details - my fault not the company. I wanted a summer weight boot that was impervious to water, sand, etc. and this boot is not. The mesh allows both water and sand to enter the interior of the boot. I do like other features of the boot. The sole is strong and when walking on gravel it provides good support as does the high collar to protect your ankle from rolling over. Bottom line - I love Ariat boots but I should have read the details closer.
