Big Puma golfshoe fan here (have three pairs), but... Not sure about these. The black ones look good [in the pictures], but I'm not sure about the white ones. They look a bit "orthopedic." Maybe they'll look better in person.
I'm quite new to the site, and mostly I just lurk around, but by coincidence I received my pair of black and white swing GTX today. Bear with me and I'll give you my opinion . I think that they look cool enough, kind of 50's style but not too flashy like to golf concords. They're very light, rubber coated fiberglass soles and light weight insoles. The soles are very stiff, I'm switching from JL classics and notice a huge difference. Mostly though I'm impressed by the new quill soft spikes, dozens of them. They grip like the old metal spikes and don't leave a trace on the greens. Plus they're permanent, so you never have to sit around changing them. The spikes have a two year warranty against wear, I called puma canada before I bought them, "... any noticeable wear to your displeasure and we'll replace the shoes." The spikes are all arranged at angle's to provide grip concurrent with a golf swing, not straight up and down like metal spike. I'm enjoying mine, highly recommended.
the shoes aren't wide - I fit into same size as I do the 360 Ltd. Different than the Adidas in fit though, not as mushy for lack of a better word -comfy, yet firm...shoe fits like a slipper, outsole is real stable.
Both shoes are as sick as golf can get. Next up Black 360 Ltd with white stripes (ho...)
I got hold of a pair of the prototypes from Germany in Jan. They're a snug fit width wise Clinton. But if they're anything like the PG GTXs they'll stretch out.
