The description said these shoes were leather uppers.  This is not true.  They are are man made leather, and they don't breathe well.  The first pair I wore, it felt and sounded as if they grinding and dissolving off the soles.  When I took them off to check the soles, they were indeed disintegrating in tiny pebbles.  The left shoe was quite a bit smaller in width then the right shoe, and my feet were wet by midday as well.  I returned them, Amazon replaced them.  The second pair are a both the same in width, and are not disintegrating in the sole, but still do not breath.  I would not recommend buying these shoes, they are not the same quality that I have known before from Ryka.  Quality of materials is not what was from other Ryka footwear I purchased prior.  I am very disappointed in this company, since they have reduced their quality of their products.
