(UPDATED REVIEW AT THE END)

I DEFINITELY RECOMMEND ORDERING A WHOLE SIZE LARGER THAN NORMAL.

I normally wear a size 6 across the board. Only once in a great while I have had to buy a 6.5 and that is usually with sandals. I ordered these Reebok's in a 6.5 since I had heard they run small and the 6.5 is still VERY snug on me. I thought maybe they would lossen up some after wearing them, but it isn't happening. It is to the point that my feet are literally going numb, they are so tight. They look big enough but once I put them on, wow, they are tight. I think it has something to do with the padding inside the sneaker. Even to hold them up to another pair of my size 6 sneakers, these are a little longer, so it has to be something on the inside making them run so small.

I have worn them all day and evening long for 3 days, hoping they would loosen up, but as I said above, no such luck. I haven't felt any difference in my legs while wearing them this very short time period and am hoping to have better results with a pair that fit properly. Boy do my feet feel sooo much better after taking them off! I can't believe they run so small. I have never, ever wore a size 7 shoe of any kind, but apparently that's what size I need with these!

They do look ghood and seem to be well made. I didn't notice my stability to be "off" at all, which is how they are supposed to work..but again, maybe that has to do with not fitting properly. The soles (the actual bottoms, the pods on the bottom) feel good. It cushions and presses in when you walk. They absorb impact very well because of the pods.

I ordered mine from EastBay in order to take advantage of Bing CashBack and I am going to return them for an even bigger size. Thanks goodness the shipping was free and free returns.

UPDATE AFTER RECEIVING CORRECT SIZE:
I have been wearing the size 7 now for 2 weeks. They fit MUCH better. I did have to "break" them in a little still though. I have to say that these are really comfortable now that I have been wearing them regularly. I am on my feet constantly at work, and again when I get home. I get alot of walking in at work though and I have a physical job and these sneakers have been great in a variety of ways.

First of all YES I do believe they do SOME toning. I believe this because I can FEEL it in my legs, thighs and butt. These sneakers are by no means a replacement for exercise, but rather a boost to the activity you already do. I already walk a ton, to these give me a boost.

Secondly, since I have been wearing these sneakers regularly I have a significant decrease in back aches/pains. I am telling you I used to have back aches every single day after work. It was to the point that once I stopped moving for a minute or two, my back would feel like it was stuck and I couldn't move and it just ached like crazy. I can honestly say without a doubt that these sneakers have reduced that problem greatly! I have almost no back pain at all since I have been wearing them. That in itself is amazing to me and even if they didn't provide the toning benefits, I would still buy them for relieving the back pain.

I think these sneakers, due to the cushions on the soles used for toning, greatly absorb impact and that is why they have been so helpful wiTH my back pain. That is the only thing I can think of. They feel great to walk around in/on all day. They are very cushiony. With the balls on the bottom, it feels like you are stepping onto a cushion with each step. The ball things are soft kinda and push in as you step down.

I have never been a Reebok fan but I gaurantee I will buy more of these sneakers once this pair wears out. The comfort level and the decrease in my back pain/problems has me absolutely thrilled. The toning benefits are great too, but it is a close tie with relieving the back pain. That was an added, unexpected bonus that I am grateful for. I am so glad that I decided to give these a try and I do recommend them for the toning benefits and for relieving back pain. Totally worth it. JUST MAKE SURE YOU BUY THE RIGHT SIZE - A SIZE LARGER THAN USUAL.
