Hello, Shoes are ok, but heel size is not 5.5, but something between 6.5 or 6.7 inches (16,5 cm - 17cm) in size 12. heels size is high, that's ok, but arch of the foot is very pronounced, making the shoes very very difficult to walk with. I have another pair of stilettos with 6.3 heels and there's not issue to walk with. My opinion is it's the last shoes before ballet heels shoes. Let's see if with some training I can finally walk with.
My advice: Just like all shoes and boots with this sole, these fit one size larger. I wear size 46 but with these I had to order size 45 (14) which fits perfectly.
