The first time I put these on, they felt fine.  After 30 minutes of walking around however, my feet began to ache.  I love the fact that they are so heavy duty, but I can't wear them for more than a half hour before my feet become too uncomfortable. I don't think this is a design problem, just my feet can't get use to the hard toe. If you can wear a hard toe shoe without that ache, these might be a good match for you.
