These work for me ...

Obviously like all large boots make sure there is space around the rudder pedals, while the Antares should be fine my ASH-26E can get tight.
These are not hiking boots but more err on the very comfortable and warm side. If I was on a serious XC or worried about a landout I'd throw a pair of hiking shoes/boots into the back.
