Returned due to 1/2 size to big - I have similar J-41 shoes and thought I'd wear the same size in their splinter company shoes, too.  Wrong - Jambu runs a bit larger than J41.  Since Amazon doesn't do easy exchanges as does Zappos (which Amazon owns) I just returned these.  Wish they would - then I'd have tried the next size down and may have loved these since they are so fab looking & have good cushioned support.  I was too tired to cope with re-ordering after it took 2 weeks for them to process the return.
