PROBLEM: Review: The book stands on its own, though I found the ending disappointing. I downloaded this in order to be able to follow the more obscure passages of an audiobook version and it was excellent for that purpose; the digital edition worked just fine on my iPad with no difficulty in locating specific sections based on the section and chapter breakdown. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I guess these would be good if you had foot surgery and wanted to place something lose and protective over bandaging, but not for under a boot cast. I was under the impression these would be tall enough to almost reach my knee. They only go about 4" above the ankle. Very wimpy, probably wouldn't hold up to too many washes. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: This product does suck you in Great !! But the bones in here tore back back up, I had all kinds of bruising when I took this off after wearing it all day, they need to make one smooth with out the bones. 
 Polarity: Negative
