From what I can gather high profiles sit a bit higher and are more rounded so you get more projection. Low profiles are a bit flatter and wider and tend to be used on more broad women, although that’s no always the case. I had 485/415cc high profile soft touch overs and my friend had the same but in 380cc and low profile (she started off slightly bigger than me) in december so will be able to see the difference in a few weeks xx
