I haven't used any of the crazy expensive spikes. And I don't see it happening any time soon. Everytime I forgot mine I had to use someone else's, they were always uncomfortable. I bought these Klein, and bought the velcro weaver pads for them. N they are great. I absolutely hate when I have to use anything else. Idk if it's cause I learned how to climb with these or what. But to me they are 10x better than the standard Buckinghams. The support is great, comfortable, sturdy, dependable. I love these things. And I recommend them to everyone.
