I have been a runner for the last twenty years.  I'm not a fast runner, nor do I run super far.  I typically run between three and six miles each session at about 5.5 mph.  I have been wanting to try a "zero drop" or "barefoot" shoe for quite some time now, and finally took the plunge with the Pace.  My first run left me with severe blisters on the backs of each foot--I expected this.  I had run about 2.5 miles when the blisters formed, and continued another half mile.  I had to wait almost a week for the blisters to heal.  On the second running session, I was able to run 3.5 miles, blisters formed, and I kept going another .5.  A week later I ran again, and this time did not form any blisters at all.  This is pretty much what I expected.  My feet are now used to the Pace!

These shoes feel GREAT.  They are super comfortable, light-weight, and flexible.  Furthermore, I am convinced that my running efficiency is far better with these shoes than with any other running shoes I have owned over the last twenty years.  My form is better, my breathing is better, my gate is smoother.  I'm convinced it's because of the shoe!  I cannot say enough good things about them!  Finally, I found my shoe!!

People who seemed to give negative reviews maybe did not understand what exactly they were purchasing??  Do NOT purchase these shoes simply because they are cute (and they are indeed cute).  Do not purchase these shoes and try to wear socks with them.  They are not made for that!  Do not purchase these shoes and expect your foot to easily slide in...duh, it's why they are called Pace "Glove"--they fit like a glove.  Yes, they are tricky to get into, but once they are on, they are great.  Do not purchase these shoes if you're expecting arch support, or the like.  This is not what they are designed for.

I am a true 8.5, and I purchased an 8.5.  My feet are probably on the wider side (very slight), and these shoes fit perfectly!  ...plenty of room for my toes!  The only place I got blisters was on the heel, and that problem is gone now.  This shoe is sooooo comfortable.

Pros:
1.  Super cute!
2.  They actually do stay dry--feet do not sweat in them.
3.  Comfortable
4.  Super light-weight

Cons:
1.  If you run on a treadmill, they are louder than a "normal" running shoe.
2.  If you run extreme distances -- more than 8 miles at a time, you're feet may ache a little.  But that's just a hunch on my part.  It could just be my old feet!

I will DEFINITELY purchase this shoe again.
