These are my "go to" shoe once spring weather arrives.  I have two pairs, one in grey and one in black.  I don't think they make the grey anymore.  I can wear these all day and walk back & forth to work (2 miles each way) with no problems.  I have really sensitive feet and most shoes I buy end up hurting my feet and spending the rest of their lives in my closet.  But these are good.  I like how the rubber is malleable, it doesn't bother my feet at all.  The only thing that bothers me by the end of the day is the textured foot bed.  By the end of the day, I am just DONE with those balls rubbing on the bottom of my feet and I can't wait to wear something smooth.  But that is my only beef.  Oh, also, these are great rain shoes.  I don't like wearing rain boots because my feet get so hot.  So I always wear these in the rain -  - - you have to be careful that your feet don't slip out, but I find these really comfortable to wear in the event of a light rain.
