I have worn grasshoppers for some 30 years--from April to Thanksgiving--these are pretty much the only shoes I wear, day and night.  I usually buy 2-3 pairs in late August to have in the Spring and for special occasions.  They wash nicely, also.  They are the most comfortable shoe ever.  I ordered them on Amazon for the first time--not a price difference, but convenient and lots more choices--and am pleased.  My suggestion is to know your size in these shoes first before ordering, since shoes can differ a bit.  (I do not have arch concerns so am not real sure as to how much arch support one would need but they are certainly comfortable and give me plenty of support for long periods)
