I bought these to have a lightweight option to wear on dry days in the field. They're extremely comfortable and lightweight, but they'll never see the course. After 2 months with only 2 club fittings and 6 training sessions, the blue sole has separated from the gray foam part. 7 of the 12 lugs are also completely worn out, which seems to be at least twice as fast as any other lugs I've used. I inflate the rider in the 110-185 km/h range, so that doesn't mean I put power in the shoe for long rides or even pga. They might hold together for folks swinging under 100 mph, but I don't think they'll last much longer than mine for those swinging 250+ yards.
