text: Loves these shoes but after my 3rd pair these will be my last. The &#34;tubes&#34; design is amazing and is a really soft walk and good for your feet, but I cannot get good wear out of these shoes. The constant flexing of the tubes against the actualy sole of the shoe always breaks and I've only had mine for 5 months now and have resorted to super gluing them back together. After the 3rd pair, enough is enough. This pair I have also noticed the heel tubes seemed to wear out quicker and so I therefore get a lot of flex and I've noticed my ankles are sore at night from what I can only assume from the strain of trying to stay balanced? (PS:  No, I don't deliver mail and walk all day. I work an office job 40 hours a week. Yeah.)
