I am buying a new pair of these because they run small and actually fit a size 4 (unlike most Naturalizer 4s) and the style is contemporary and not so conservative/old lady (sorry!) like most 4s I find- usually either nurse-like flats or sexy stiletto heels, so the Oxygen is a great in-between style.<br />But the quality? Ai yi yi. The leather has already separated from the cork, and the sole has become unglued after only a month of occasional wear. The footbed does cut in somewhat, and the strap does rub. But there's no trade-off for a shoe you like that actually fits your foot, and here I am buying pair #2 and sending pair #1 off to the shoemaker to be fixed. What can ya do?
