just picked up a pair myself and love them. Used stabalicers in the past but got a new pair of boots and the stabilicers don't fit them well at all. The microspikes are a great fit to both my old and new boots. The new design beefed up the rubber part and gave it a 2 year warranty, their customer service is a 1 year. i emailed them and they asked is it a 2 year or a one year and they said its a 2 year for any thing i don't like no questions asked full refund and than a1 year after that for any problems repairs etc. No registering or anything so im not sure how they know when you bought them to start the 2 year + 1 year warranty but i guess it's a loop hole! Awesome product and very stable, don't see anything happening to them in a very long time.
