First, have been playing spikeless for a couple years now. Saves the bother of periodically changing spikes, or even needing to change shoes at the course. But there has always been a bit of a problem under certain conditions - now and then they'll slip a bit in the sand, or on wet tee boxes while taking a full swing with a driver.Played with these for the first time today, and I must agree with what a few others here have said. Someone finally figured out how to make a spikeless shoe that really grips the ground. A couple of the tee boxes were a bit damp (got out quite early, and some morning dew hadn't yet been dried out - the exact conditions I usually worry about with spikeless). Was really pleased ... these were rock solid. (If you're considering buying, magnify the photo of the bottom of the shoe - what they did was genius).I know a couple folks here complained about sore feet or something, but I did not find that to be true. They are light, and had plenty of arch support, at least for me. I walk when I play, and these were quite comfortable, and completely broken in by the ninth hole.So - I thoroughly recommend them.But here's the "however" ... I am built slightly, with thin feet, and these fit pretty snugly, especially around the toes. They relaxed slightly during the round, and are now absolutely perfect - for me. But they might not be a good choice for anyone with wide feet.
