I hear what your saying. I don't mind the additions being available. It might make it fun to accessorize. I just don't agree with them actually improving performance. We could then begin to argue that anything improves performance, like a vizor giving you better vision on a sunny day.
Many golfers choose to golf without a glove altogether, particularly with advancement in in grip technology. I'm trying to migrate to this myself on days that aren't too humid. Also, I would say that for most, shoes aren't that instrumental to performance either as there's a tour player that basically plays in Vans.
I just see it as a slippery slope of increasing performance. Where does it stop. Shoes, gloves, vizors, sunglasses, tees, grips, club-cleaning brushes and towels, sports drinks. Some of these items would seem to give a golfer more of a mental edge than a physical edge. As a former great FSU cornerback once declared, "Look good, feel good. Feel good, play good."
I respect your opinion as well and just presenting an alternative point of view. Take care Sting.
