When I first tried these on all I could think was &#34;wow&#34;!  They are extremely cushiony feeling and as a heavier person who is trying to start running, I thought that might help lessen the impact on my joints.  The price put me off a bit, so I decided to think on it.  I went to my local running store (which is a farther drive) today to try them on again.  I looked at them in comparison to a few other shoes and they felt by far the most cushioned.  I jogged around the building briefly and they felt pretty good, so I went ahead and purchased them.<br /><br />I took them out for their first walk/run this afternoon.  At first they still felt good and I liked the cushioned feel.  As I started running after a walking warm-up, I noticed my calves hurt - which is unusual.  I kept my running intervals a bit shorter and walked more in between.  By about 3/4 mile in, I noticed my feet were feeling almost pins and needles like they were getting ready to go numb.  I've had this happen with cheap shoes before, but was not expecting it with these!  Once that started, I slowed back to a walk longer and started paying more attention to how my feet were landing.  I have a neutral stride and these were definitely making me land on the inside of my heel with my arch almost collapsing to the inside - basically making me over-pronate.  I finished walking the 2 miles and only jogged a few strides here and there to test them more, and noticed that unlike my other running shoes (Saucony Ride) which have a nice breakover to roll me to my toe to push off again, these didn't have much breakover at all.  It took a lot more effort to push off with every stride due to the excessive cushion.  By the end of my 2 miles of mostly walking with intermittent jogging, my achilles was sore as well.<br /><br />Though the cushion seems like it would be nice for someone who is new to running or on the heavier side, I can say that it did nothing but make me work harder.  I took them back to my running store immediately and exchanged for the Brooks Glycerin 13, which are in the same category and same price and still feel good even if the cushioned feel isn't as evident from the first step.  The Nimbus 17 might work for someone who naturally supinates, but was not at all what I was hoping it would be.tore immediately and exchanged for the Brooks Glycerin 13, which are in the same category and same price and still feel good even if the cushioned feel isn't as evident from the first step.
