posted this in the G Spot, didn't realize we had a dedicated winter hiking sections :)
anywho- not sure how long these have been out, but pretty slick idea- adds 5" of flotation to your shoes when you need it (remove when you don't)
BUT they supposedly only work on the new shoes- seems like they could be retrofitted to the older Lightnings- has anyone tried??
I've got 25" shoes, there definitely have been times I wished I had 30" shoes- be nice to have the option
