These have excellent arch support and the elastic helps give my very high instep the flexibility it needs. Even so, it fits with a lower profile against the instep than the professional does (the professional has padding at the instep). Right out of the box I put them on and they fit true to size - I wear a 38 in the professional and the 38 in these fit me perfectly - and I took them for a mile and a half walk through the park without a problem.

Great arch support and structure, just like the other danskos I've worn.
