I have worn out three pairs in one year...  OK precisely 2 pairs (the last one is on it's way out) and I ordered two more just last week. That tells you my love/hate feeling about this pair.  Good: very comfortable and very good support. I used it for Zumba and Cardio Jam classes. I also use this pair as my walking shoes between home and work (I change to my work shoes when I get to the office). Walking distance - 20 min in the morning and 20 min at nights. Weekend, prob a few hours each day.  And yet, only after about three to four months, the seam in the back started to torn and fabric got worn out and loosen up... I LOVE this pair of shoes as they are so comfortable, supportive, light-weight and stylish (I have tried different brand, like Nike, New Balance and etc). However, I am really hoping Ryka will consider to re-design their seam and the fabric used inside... It is just not acceptable for something that cost $60/pair to last less than 3 or 4 months!
