On modified last, your best bet would be Moulded Shoe, but even then, No. If you want them on that last, you'd pretty much have to buy those. Maybe Moulded has something similar non-shell.
Alden Madison has something similar on the grant last. DC and SF have something similar on Grand with commando sole. Also, Shoemart, as mentioned above.
Actually, much to my surprise, Moulded does have that boot on their website!
