Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.

I am sorry to all of you who like this book but I would never wish a single soul to read this. This book has the plot: a girl goes to a farm, falls in love and everything goes wrong. The book just goes on and on. The only reason I read it was because my mother asked me to. This book could have been written in 50 pages but no. It goes on for 300 some odd pages. I would have rather read the dictionary. The only reason I give this book 2 stars is because there was maybe four parts that consisted of 2 pages that were mildly interesting. Take my word for it. This book should be skipped.

I bought this for a friend for her birthday and it didn't have a picture posted but from the description I figured it was the old version without the scary lady on the cover but it wasn't. Oh well.
