I have heel spurs and don't want to give up walking the course, so decided to try spikeless. I tried on Ecco, Footjoy, and Adidas, but each had something I didn't like. The Callaways suited me because they are more "substantial" than the others that I tried, and both felt they had the flexibility and cushioning that I need, while still offering good lateral support. I also liked that the sole design is a little more elaborate than just nubs. My only worry was if they are waterproof. The first time I came off the wet course, the starter said "you're feet must be soaked in those shoes!" In fact they were completely dry. Another day I got caught in a downpour without my umbrella, and when I finally got back in, only my feet were dry and warm! They seem to work for Ernie Els too....
