Let me explain further that the combo of a softer rubber,full herringbone pattern will allow for greater flex despite deeper grooves and not trap clay or dig it up becuase of the added flex.Smal herringbone pattern like on the PS 1000 by Wilson don't do nearly as well as the Barricade 3's grooving, but shoes like the NB 1000 have full herringbone in a softer rubber and despite it's mesh upper that gets dirty on hardcourts it does just fine on clay.It may do just fine, but there are better shoes than that for clay specific use.
