I found these on Amazon and would like to hear your thoughts?

They're Vibram- that's supposed to be good? I would like thinner soles that would perhaps with better grip- I slipped like 3 times with my leather soles.

I do love DIYs and this would be a wonderful challenging project of course with prerequisite research- definitely don't want to ruin these shoes.
