Firstly, if you read a negative review that these shoes can't withstand real running conditions, ignore them. When you buy these you think they are the right shoes for runners. Even if you choose them for comfortable everyday wear, they are perfect. Super light, super comfortable, at least decent for support and amazing durability (I have three other similar pairs, one of which I've had for about 4 years, which is used as a water boot for kayaking and boating, and they take abuse and through the puck running and showing no signs of damage). worth your money.
