Design: a matter of taste ... each as he wants.
Fit: I have previously disclosed the same fins ordered in size 44/45, as I have I read here in the recessions that this model is like "a glove" fit. This is not like that. I have pointed out, the next smaller size (42/43) ordered, although I shoe size 44 / 44.5 have ... I have to say that fit like socks. Perfect fit, nothing slips etc.
I oriented myself to the following table before I ordered the 2nd pair:
[...]
Feet measured ... about estimated the corresponding size (1: 1 ... with no additional air to hit it or the same), I could also choose ... and ordered.
Not afraid you to order the fins a few sizes smaller than you are used to when buying shoes. When in doubt, order and test 2 pairs.
In the area of the ankle bone, I have my standards a little "too much" air, but is merely the fact that I have a rel. have narrow feet.
Material:
The choice of material I find quite well so far, everything feels very comfortable on, expresses nothing, nothing pinches.
Whether the whole is, however, also durable, I can only say after the holiday. For this follows next month (mid-Aug 14) nor a comment.
