Please go see a fitter. This isn't really stuff random people on the internet can help you with.I am in the same situacion that you. I have tried the Edea in 250C and it is ok however, after 20 min i fell pain in the heel and the left foot it falls asleep (I think I think I have a problem with my left foot, the same thing happens to me with all the boots). The risport in 250C is very wide, however the fitting chart looks wrong because the 245C is correct in wide and the measure is similar to 250C according to the table.
I order for the 250B because they cannot be returned.
Do you order the 250B? How do you feel about them? could you tell me the width of your foot?
(I have 12 days to return Edea).
