I bought a pair of the Atan Sunfasts one size smaller as recommended but found them to be too tight.
I have since bought a larger pair and love them - really comfortable and slide in and out of the straps no issues (I sail fanatic boards so straps are very ggod).
If anyone wants a new pair of Atan Sunfast boots, size 44 - 45 for $50 pm me.
