They are excellent shoes for running on uneven ground, I use them as a valet because I have to run through streets up and down stairs in all manner on conditions and the weight is cruical along with the grip. I did "blow out the sides" on both my baby toe but its not an uncommon thing due to the width of my foot. This ismy 2nd pair and Iwill keep buying them till they stop making them. Easy to clean with good traction = a winner in my book and for the price I haven't found anything comperable.
