It looks like John will start taking pre-orders for his new loggers starting tomorrow, 5 March 2014. Like his Engineer Boots, I think these'll fly off the shelf. I don't recommend half-stepping on the decision to pull the trigger since there's never a guarantee for future runs. Delivery is TBA ... soon.
I've already locked myself in for a pair of size 7's.
