Thanks Ard, i will post updates.
As for the ProLine, the pair does not have studded soles, only plain sticky rubber.
The only concern I have with the ProLine is that it does not have the midsole drainage port to quickly drains water out from the boot.
I actually wanted to get the Field & Stream's boots but they dont have my size 11 available.
That Field & Stream's also comes with the rubber soles but you have the option attach the metal studs.
Note: The studs are just regular 1/4" hex metal screws (see below).
