One boot had a footbed liner that appeared to have been worn.
The other boot didn't have a liner at all.
If you ever place a bid on eBay for "new" clothing without a tag or box, you might want to inquire about it first. Get the seller to guarantee you that it is, indeed, a new and unworn garment, as the eBay rules state. They are not allowed to list something as new if it has been worn.
Or to play it safe, only bid on clothing that is New With Tags. Even then, you can get burned, because some people find a way to wear something with tags in place. Or they remove the tags, wear the clothing, then replace the tags with one of those retail guns that attach tags.
UPDATE August 6, 2013. eBay was very cooperative. Their buyer protection plan is wonderful and I ended up getting my money back, even though the seller completely ignored my emails.
UPDATE October 5, 2017: I have had many other disputes with sellers who list merchandise as New Without Tags and, in fact, the product is not new at all. I am avoiding any seller whose feedback score is under 99.9% positive and I am avoiding all merchandise other than NEW WITH TAGS or NEW IN BOX.
Life's an Expedition on Etsy does not sell used shoes or new shoes or any kind of shoes at all.
