I bought a pair of Korkers Streamborn this spring, they are great for support, lightweight, easy in/out..only complaint i have is I went through 4 pair of laces this year (don't even say it cause that Boa system wouldn't last me 2 outings) I'm tough on gear, I'm a big boy and I go hard..I'd imagine i will get another season from them though..
as for the soles...I had the felt come unattached from the sole on one pair (replaced free of charge ) and my first outing in the spiked soles last week..the plastic part of the sole split in several places in the cold...(also replaced free of charge)..
for anybody getting replacement soles for Korkers, I'd suggest getting a size larger, they fit better after the boot has been broken in..13 soles for my 13's were a little on the small side...14's fit snug..
