The real test came on Tuesday when I wore my new black TSUBO Acrea pumps for 11 hours, mostly standing and walking.  I have hammer toes, corns and bunions, so most pumps start to bother one or two toes immediately.  But, at the end of a long day, I still had happy feet.  Absolutely no pain, and lots of shoe compliments all day!  I bought another TSUBO in brown.  It's great to find a stylish pump with a real heel, especially at 5'3," that cradles and practically massages my feet.  I recommend them highly.
