Exactly what your podiatrist would sell you.
I have worn these for many years. I own 5 or 6 pairs. I have them in every shoe, from my work clogs to my junkie play sneakers. My 1st pairs were from my podiatrist.  They lasted 8 months to 1 yr. I tried to wear them longer and now I'm suffering  for it. I have had 1 arch rebuilt surgically and without my inserts, the other foot causes terrible pain.  These are what your podiatrist would give you in the office to support your arch, cup your heal, and give a bit of a posted(inner tilt) to your heal. They are a part of my life forever. Small price to pay as my career depends on my ability to stand at a Surgical field all day. They do add 1/2 size to your shoe. Always remove the inner sole of new shoes and place these in when trying on new shoes, BEFORE PURCHASING THEM.
