I like the Deep6 thick 5mm boots you posted in post #9 for diving wet, they work really well. But for diving dry, they're overkill, and very floaty. The regular 3mm Deep6 boots work great for diving dry, where all I really want is a boot with a grippy sole and that it be easy to put on. At $35 they're a bargain if you ask me.
I have high arches and wear a size 9.5 EE in normal shoes. If I dive with thin wool ski socks and my drysuit's crushed neoprene socks, the 3mm Deep6 size 11 fits perfect. They're out of stock for smaller sizes, but sizes 12, 13, 14 are in stock, sounds like you need something around there. I have an unused pair of size 12 laying around gathering dust, PM me if interested, I'll send them for the cost of shipping via Venmo.
