The K5000 are not better in my opinion. Have buckles instead of laces. Also have screw in spikes which can be a pain to swap out when it comes time to replace them. Since the threads start to corrode.
I use the K 1100 PLUS series. They have more spikes than the regular 1100 series. And have push in carbide spikes that are easily replaced. Can also replace the laces easily as well.
