I had this work shoes 4 years ago, bought 2, it was uncomfortable. 2015, decided to try them again, I was impressed, my 1st week I thought to myself, gonna keep buying this forever... and ever. Then just after a month, the bottom part just fall apart. I showed to my wife and he says oh well, its past 30 days and we cant return this anymore, just put some shoe glue or something she says, and its dirty (duh, its a work shoe). Up to this, this is so comfy that I still wear them. I dont know a glue that is flexible :(.
