For me, heavy shoes are not so much of an issue. Yes, they will tire you out more, but they are sometimes more stable. The most important thing you need is to ensure it is comfortable. You are on your feet for a long time and at the end of the day your legs will hurt if it isn't as comfortable as possible.
76 today with a double on 18. Played course #4. Hit 11 fairways and 11 Greens in Regulation. No birdies! Had 7 putts inside 7 feet and missed them all! It was 37 when we teed off and 44 when we finished. Had my new 5 wood today, it was butter! Played a 540 par 5, 4 wood off the tee, 5 wood for 2nd shot then Gap wedge from 76 yards to 7 feet. Missed it.
