I love J-41 shoes.  I had this pair in grey/pink and they are getting a tad worn after a year, and my dog did a little chewing, so I got a new pair.  I think I'd better stock up before they are completely eliminated.  The insole is amazing, soft rubber that comforms to your feet, and you can really feel your toes grip the pavement when you are walking outside.  This is a barefoot style, so not for everyone.  I wear them to the gym, zumba, around the house, and even on long walks.  I fall and trip a lot, and I think these give me stability and traction.  And I always get lots of compliments.  I wore my grey pair to the airport right after I got them, and I forgot to take them off when I went through security, they were so comfy.
