I was eager to get a pair of these to up my walking regimen a fitness level. I like the look of this black pair the best, although I don't care for the look of the thick sole. First impressions on the fit are that the sole is very cushy and springy, and because you can't rock back on you heel, you maintain a straighter posture.

I've worn Shape up both for light hiking on a good trail and walking outside, as well as on the treadmill. It definitely made my light hikes more challenging than normal. However, I found I got cramps in my arches with the shape-ups and my calves, thighs and butt got a more solid workout.

On the treadmill, I liked the springiness of the shoe, but definitely found my right hip ached if I did my normal treadmill program (walking on a medium difficulty at 3.6-7). The ache lasted for a up to a few hours after my workout. S

Pluses: Works your calves, butt and thigh more at any level of difficulty. Soft cushioned sole and springy step, as well as better posture while wearing Shape-ups. Good deals online when you can find them. I paid $65 from JCP online. They had a sale at $79 a pair and I found a discount code for JCP at $15 off any order.

Minuses: Puts pressure on weak areas and may cause discomfort or pain for some people. Attractive style but still not very sleek. Higher sole requires care in walking so you don't twist your foot or ankle by accident (like you might walking in heels). Pricey shoe if they don't work for you. Good walking shoe, but I wouldn't hike or run in these.
