I've had a number of running and hiking shoes, but this one felt like gloves on my feet the very first time I wore them. There absolutely was no breaking-in period. These shoes are very light and nimble, low to the ground. Yet your feet feel protected.

However, note that these shoes are not water-proof, nor wind-proof. Not the best to run in the cold or rain. But when the weather is good out, you will feel like flying in these. Build quality does not look to be the greatest, so I'm not sure how long they will last.
