This thread may become more political than we want it to, but I'll put in my two cents. I question the effectiveness and appropriateness of approaching this problem by legislation.
I think economic means are likely to work faster and better, what you buy communicates well, and if the demand develops, manufacturers will respond.
I'm nervous about getting an "inappropriate footwear" ticket if I go out without boots in the snow, and I see that as likely where I live (Massachusetts). Don't want to give the government too much power over personal decisions.
Many different views will exist on this, this one is merely mine!
