CALZUROClassic Work Clogs with Holes - Unisex Work Clogs for Women and Men - Non Slip Shoes - Autoclavable Rubber Kitchen Shoes and Nursing Clogs

For a size 8.5 should I order 38/39 or 37/38? Both say they fit a 8.5?

Buying these for my brother who likes red, but when he got those, they looked very pink - does anyone have the maroon? Look more reddish?

What is the exchange policy if the shoes does not fit? I am a 6.5 and would like to get it with the insoles. Should I order 34/35 women or 35/36 women

Are they sold in stores? I like to try on before buying.
