I bought these for my mum who loves walking on the nearby sand dunes. They are very comfortable, but feel sturdy and supportive. The sizes are quite wide, as per the description, but the adjustable straps allow you to tighten them up if necessary, ( though you can only adjust the straps in two places not three as stated, there isn’t an adjustable back strap). They haven’t been washed yet, but haven’t needed it, as the sand brushes off easily. When my existing walking sandals wear out, I will be getting a pair for myself.
