Well the selections the way they are written make no sense.  I've been wearing size 9D shoes for the last 30 years.  Prior to order it from Amazon I tried them on at a local shoe store.  The 8.5's fit perfectly but they did not come in the waterproof.  So how do I rate these compared to all other shoes that I've worn these are half a size bigger. So did I expect them to be half the size wrong? yes I did.  So the way Amazon writes, are they as expected or too  large.
