Do these have extra white laces? Gazelles are supposed to have a pair of laces that match the color of the shoe and a pair of extra white laces.

Is this shoe a women's or men's shoe? I would like to buy a pair to fit a men's size 10.5

I plan o leaving these in the trunk of my car to change into when i get off work but it's extremely hot here,triple digits, will they melt in my car?

Are these narrow?
