Sorry to bring back an old thread, but I bought my first set of golf sandals this spring and they are great. I bought the Foot Joys sandals. I am playing more golf than ever this year and I credit the sandals for helping to bring about more consistency in my game. Wearing sandals forces me to pay closer attention to my stance and alignment and it makes me slow down my swing. The result is better ball striking and fewer pulls.
For hot days they are great, my feet feel so much cooler(making my whole body feel cooler) and although bunkers can be a pain, I'm not in them as much. Yesterday I played my personal best round at Carstairs (83)wearing the sandals, two strokes better than my best round in my Ecco shoes.
Of course, as with all sandals, socks are NEVER worn.
