For wet footers, just got back from a one week trip in the French River Provincial Park with the boy scouts.  Used Teva Gamma Pro shoes.  If you have good ankles, these were very good shoes.  Tennis shoe height, good mesh, only stones ingested were from over the ankle area and they were very minimal, gripped wet rock very well.  Grade high B, don't know what an A grade would be for shoes.  They worked very well.
