~ I really wanna buy these for my 2 son's ( twins ) they are 3 1/2 yrs old 35 pounds.... how do I know what size to get them && how many winters would they be able to use them for??
The size options are by foot size. It starts at 11C and goes up to 3. Each boot will actually fit two shoe sizes, so the 11C is a 11C then by removing a layer of the footbed it becomes a 12C. Go by their shoe size to get the correct size. 2 years minimum.
