The instruction could be improved, but overall the product was pretty easy to assemble and install. That gives everything kind of a flat, dull look. These, coupled with the Yakima Timberline Tower 4-pack kit made everything work like a charm. I love these slippers, I have very wide feet and am a diabetic, I need to wear something on my feet most of the time and these fit any foot and my first pair were about 5 years old before they started to fall apart and even then it was the sole that was breaking the rest of the slippers were just fine. Also good robust sole and reasonably light weight. When not wearing them, she pretends they are unicorn babies. Im sure these are fine all day for anyone with good circulation or for a quick trip to the store for someone with my issues, but if youre looking for something to wear all day and your feet swell, look for the Sketchers slide sandals style with the wide band that cross in an X over the top of the foot. In some reviews I have read that these are made in Australia. So disappointed in this purchase ! The backpack secures up to three tennis racquets.
