Received my 6" Explorer Light boots yesterday, wearing them around the house now in case they have any hot spots or issues. Been 3 hours, super comfortable right out of the box. I wear a 12.5 but ordered 13's as I always lose a big toenail or two on steep hills and needed extra room in the toe box. Question was if my foot would slide down and then have my toes hit the front of the boots, so far, no! Can't really wear them outside and return them but so far, even standing on my toes, my ankles and feet are staying put and as I said, toes aren't smashing into the front of the boots. Looks like I'll keep them and take them outdoors. Good quality made boot and I especially like the padding around the top of the boot. I did email and call to discuss the right size before purchasing. Looks like they gave me good advice on sizing. Might try some insoles if I need them. Have had Crispi, Scarpa, Kennetrek, and most others. I do have high insteps so I need comfort on the front yet still need to have my feet secured. Thanks Hoffman!
