I am selling a pair of Burton Photon Wide boots with the BOA system. I used them for about 10 days during one season. There is no hydrolysis or sole separation. I tried to pull them apart once, but they were fine. I don't feel any significant loss of flex. There is some peeling on the surface where they rub against the bindings. Thank you. - Brand: Burton - Model Name: Photon Wide BOA - Size: MNS - Color: Black - Features: Easy fit adjustment with the BOA system Thank you for looking.
