Can't go wrong with Danner and their reputation. I was a bit worried buying them online without having tried them on first. I am an 8.5 and with a standard-thicker sock, they fit perfect. I think if I wanted to wear them in winter with very thick socks, or doubling up, it might be a bit snug (but I have real winter boots, so that's no big deal). The seams are right and I like that the soles come up high around the heel and up through the toes. I find that my most wear on my boots are in these areas (my heels seem to scuff each other and I'm always banging my toes into things) so having this reinforced with the rubber will help. Tred seems sturdy- looking forward to breaking them in and making a mess outside!Incredibly fast shipping- they got here before the estimated delivery date! what a delight. thank you!
