    My son used them ice fishing this weekend and had no issues walking with them in the snow or on the ice, they are a little hard to get on because they are a little tight around the top of the ankle area, I would recommend going a size bigger

    I was hesitant to purchase these for my 2.5 year old twins because I read a review saying they were difficult to put on; however, I don't find this to be the case at all. My twins often surprise me by putting them on themselves and begging to go outside. I bought a size larger than their true foot size, just in case, and it seems like this was wise. Great for the Montana winter!

    Great winter boot but hard to get on

    This boot is amazing for warmth and durability and I love how high up it goes. The only downside is it is really hard to get on. My 2.5 year old won't wear because he gets frustrated his foot won't go in. I even ordered a size larger but with the liner in it's just too hard to get on. My 7 year old struggles to get hers on as well. So we have brand new boots that are amazing and my kids won't wear them. I'd still recommend this boot. I'm hoping we can break them in a little and they will have an easier time getting them on.
