I have just returned from Australia where I bought my future daughter-in-law a pair for £75. These are the ones guaranteed for temperatures to -30F (she and my son have moved to Chicago). I am not sure if the Florida ones are genuine Australian made but one thing we were warned about in Australia is that there are lots of Chinese made copies around which are not the same quality and the soles are not suitable for wearing in snow/ice.

I wished afterwards that I had room in my suitcase for a pair for myself as I will no doubt be visiting them during the winter so I have since looked on the internet and found this site in Australia which has some good deals on at the moment for Aus.$129 (about £54) plus £9 postage.
