Query: Do NOT buy

Do NOT buy this product. I had foot surgery on 4/27/2011 and went to take a shower on 4/29/2011. I used the product exactly as instructed and my bandage became soaked. Called the surgeon and he asked me to make immediate trip to have bandages replaced to attempt to prevent infection. We reviewed the Xerosox and realized it had two tiny holes at the bottom - that's where the water came in. Called Xerosox and they didn't stand behind their product. Go elsewhere! This could have been dangerous.
