Little did I know that these "Margaritaville Men's Dock Slip On Boats" are NOT the same design as the previous Margaritaville Men's Dock Slip On Boats that Revain sold last year (2019). This year's version is essentially flat sole and heel and for me this design is very heavy on the feet. I'd love to see Revain bring back the original men's Margaritaville Dock Slip On boat shoe. While this new style seems sensible and has a nice design, of course they're back to Revain.
