0cm?????????????????????? It was easy to assemble, mine came with tremendous welds that I inspected. These were my wedding shoes. They did fit properly as far as length and width. These are warm, look exactly like the Uggs and are the same height sitting side by side. These are super cute, but don?t fit as advertised. Plus I am having such a hard time finding white shoes that I like. Very comfy, my boy loves them I bought my first pair of these White Mountain Harley Footbeds about 3 months ago. Freezing, locking up.
