what about adding a metal eye bolt to the top of each one and then use a length of one wrap velcro. this will rip away if pulled hard enough, just make sure it's only one wrap and not more than one. you can tear this stuff with your fingers, but it will be strong enough to hold it in place. try it and see what you think. i would want the ones that have the points retracted tho.
i don't worry about spikes wearing a float suit. i just use my elbows and back and kick to get more of me on ice and then bend the knees and roll away from the hole.
this works best for float suits in my opinion and i have used this method. the suit wants to keep you on your back so why fight it and make it harder to get out.
