After 10 months my shoes finally quit on me. They're really great and help me with my flat feet so I did my best to try and save them. First I attempted krazy glue but that didn't work. Next step was the Plasti Loka that they use for patching up holes in the plumbing. Thats what the green stuff is. To avoid the apearance of gum on my shoe I decided to cover it up with good ole' sharpie. Today we headed out and I was so sure that the Plasti loka would hold, but not five minutes of walking and it ripped open again. It's hopeless.
