As with regular birks, your feet have to get adjusted to them (they have to form to your feet) so the tops of my feet have some cuts from the top part rubbing on them. Overall I recommend it for a decent noise cancelling headphone with good sound. I love that you can turn a knob to tighten the hitch receiver so that the rack doesnt move around. anyways decided to order a different cord from another seller to see if i will have more luck on the longevity of the cord next time around. I got him a size 8 and it fit perfectly. The product is described as opal, however it?s not shiny or opalescent. A good fit in this situation is different from a good fit for walking purposes. If not for that gap I would have kept these. The sneaker is very comfortable. Get them, youll thank me later.
