First, I love Oofos.  My podiatrist recommends them to all of his patients and, when I'm not at work, I'm in my Oofos but the Oolalas are not up to the same quality.  As others have mentioned the metallic look to the straps is painted on and the paint wears off very quickly.  I also found the Oolalas to be much less comfortable than regular Oofos.  The post (shank) on regular Oofos comes straight up while it angles back on the Oolalas and pressed between my toes.  I could only wear them for short periods of time.
