I have a history with Merell products and have always appreciated the comfort and quality. I selected this boot after careful consideration knowing that I needed a boot that would be comfortable for long work periods, stylish, easy to walk in, waterproof and capable of withstanding extreme temperature variations. My job takes me from 70 degree hospitals to a cold soaked helicopter where outside wind chills that can reach -40 degrees and colder. This boot could not be cumbersome or heavy as I need to be agile and able to operate controls with a degree of feedback feel and in tight compartments. The Moab Rover, so far, has demonstrated that it will meet my demands. I haven't tested it in the snow and extreme cold yet but it feels right. The width on the new boot seemed snug at first but I'm confident it will be just fine. I enjoy walking and in this boot, sometimes I almost forget I have a shoe on and I find myself thinking, this feels good! Thanks Merell.
