I liked the mini lug threads better than the bayonet lugs. You are safer. I usually wear clothes that are 10.5 or 11 wide. I'm a size 11 and they fit me. As you get a little taller (half a size), you can add shoe inserts for a softer feel. After playing 3 rounds of golf in it, I realized I had lost a spike. When I added the replacement tip, I checked all the others and found that they all needed tightening. Most of them have made at least one complete revolution with the tool.
