I got my pair in last week from lathrop and sons and wore them all weekend in 98 degree temps outside and shooting my bow. I am going elk hunting in sept in colorado and believe they are probably the most comfortable well built boot I have worn. I also own kenetrek mountain extreme 400 and they are awesome too. I wanted a uninsulated boot so I bought the alaska gtx and couldn't be happier
I told them I wear an 11 so they gave me 10.5 UK and it fit perfect. I also bought a pair of their insoles cuz I did that with my kenetreks and really liked them.
