I've been wearing the New Balance 1540 V2 for quite some time now. My podiatrist recommended them and they work great. I also have an insert that created my document for me. I was disappointed that N/B discontinued V2 and replaced it with V3. . The healing area is NOT as hard as V2 and V3 doesn't seem to work for me. Why N/B had to switch to V3 is beyond me. V2 worked great. The V3 just isn't the shoe that the V2 was. Unfortunately I had to send them back.
