Sounds like a warrenty issue. Have you contacted Garmont? How old are the boots? The Syner-G has only been on the market for a year, so you should be 100% covered. Company warrenties are there to protect you from problems with materials, and that's what you got.
Even if you didn't buy the boots from us, we are a Garmont dealer. Call Confluence Kayaks and ask for Don. 303-433-3676. I can contact them and get you some answers.
I love to dance, but who needs the music- It throws me off.
