I am 13 EE-EEEE. At age 56, I run about 10 miles a week and do crossfit as well. I ordered these because the add caught my eye, but in retrospect that was my mistake. I sent them back because they did not feel as sturdy or fit as snugly as my other NB purchases over the years (30 or more pairs over the past 30 years). My heel also slipped out partially with every step even though my toes filled out the shoe (i.e it really wasn't too large for me, just not snug enough).3 stars because I am sure these shoes are ok for a lot of people. I am happy to return and order a different model - by no means am I giving up on the only company that sells shoes that fit my strange feet!
