I have an old pair of the 360 Tours, great shoes, but the new Adidas do not fit the same as they used to. Definitely, try before you buy. I made the switch to Foot Joy, they are very comfortable. I would have looked at others, but the deal I got was absolutely insane, I’m not a huge fan of the look, but my feet are happy at the end of the round.
To your complaint, I don’t get it either, spikes wear out, they should be replaceable. I went through 3 sets not including the factory set in my 360s and honestly, they are still good enough to wear, I just wanted something new. I will be replacing the spikes in them again and using them in rotation. Mine must have a couple hundred rounds on them at minimum, I have had them for over 10 years at this point.
