being 8mm are they going to be harder to get into fins? I'm between a 13-14 do you know if they run a little smaller or larger?
Not at all. I have noted though, after several long dives in a day, that the seam along the upper/outter side begins to rub my foot excessively. Never to the point of a blister, so it's not too bad, just a note. I bought two pair and really like them.
They run pretty true to size, if you already have a hard sole and are just moving to these its fine. If you have a soft sole boot now and want to change to these size may be an issue depending on your fins.
