Pros: Comfort & Style
Cons: can slip when wet grass gums up the cleats
I got a couple gift certs for christmas & my Birthday (same day) so I indulged myself with a pair of concrete/royal blue street premiers. I must say they are comfortable as I have narrow feet and most golf shoes do not allow you to tighten up the front of the shoe.
Most of the time the grip is sufficient. However, if playing early in the morning, the wet cut grass can gum up the cleats and you loose traction. If playing 36 holes, they are the bomb for comfort.
As for style, they look great when I'm wearing my college colors on the course (Go UK!).
