The Korkers IceJack Winter Boots are available with either standard laces or the Boa Speed Lacing System. Images of each are shown below.
The boots with the studded sole is great on ice. the soles to me are not very easy to change. Should be more instructions as to how to take sole off when changing sole. At top of boot it seems to rub my leg sore when I walk a ways with them.
I would buy another pair.
