BOA M2 Replacement Lace Kit
Find a local Retailer
I've suffered from the impact of superficial frostbite for decades. Winter steelheading boots were a real problem (laces constricting circulation) and neoprene boot foot waders were a real drag. I was delighted many years ago now when I first got to use the Korker M3 Boa system--but the M2 Boas are even better. They keep my boot secure, crank down fast and smooth and never impinge on my foot. And the security of having a Boa repair kit on hand is icing on the cake. That said I love the video that shows how to do the repair and even more the woman in the M2 video's single-handed snake roll!
