I like these boots.  They keep my toes warm while I work - I work 8 to 12 hour shifts, and walk out in snow, rain, slush, and ice, to check the back of tractor trailers as they come in.  I also spend 20-30 minutes walking checking the temperatures and fuels on trailers at a shot for 2-3 hours each shift. I previously ordered OTHER boots in a size 8.  I take a size 7-7.5 women shoe, but the other boots were so small, they painfully squeezed my toes so I ordered these boots in a 9 - they are most definitely a 9.  They allow for me to wear two pair of socks (not needed, though, as my feet sweat with two pairs and I usually have COLD toes), and allow for an insole to be added and still have some wiggle room.  If I ordered them again, I would order the size 8 instead.

And, yes, on to the need for an insole... there is NO arch support, as is the case with winter boots.  When I am up and down for my job, it's no big deal.  However, when I need to do the extended walking, my back aches from the lack of support.  I bought insoles to help with this, but I think I need more arch support to counter the back pain.  The first 15 minutes are so are fine, but, after that, my 46 year old back starts to ache in the lower center.  If I were to go hiking (in the winter... ahhhahahahahahahaha!) in these boots, I would not have a good time.  They definitely lack support.  However, if you will be alternating walking and sitting, you should be fine.  They are winter boots, not hiking/walking boots.
