sizing for jet fins when diving wet and dry

[pufferfish123]

my wife has a US size feet of about 7.5 to 8.
she wears a M size jet fin ( the lighting bolt) when diving wet (those thin booties)

however i understand that for thicker wetsuit booties , and even dry suit boots - M size would definitely not fit.

qus is do can she settle for a L size fins when using BOTH the thinker wetsuit booties AND the dry suit boots ?

the idea to get 2 (or 3) pairs of fins for her seems silly , but not much choice here.

anyone with the same experience out there ?

Transfer of energy.

You don't want fins wobbling around and being unproductive. Trying is the only way to tell though because not all 7 mm boots are created equal.

Nor are all dry boots. You just have to try them.

I wear about a size 8 wide shoe and with my dry suit boot I seem to fit the XL jet fin size just about right. I slipped my wet suit boot into the XL and I'm thinking that the way the foot pocket is shaped, I may be able to get away with it for them too. I usually wear the size regular quattro with my dry suit and the smaller size with my wet suit. db
