I got a pair of tri shoes over the holidays and started using them this spring. A couple weeks ago I noticed the shoe separated from the carbon sole on my right shoe. I got in touch with customer service and they replaced the shoes under warranty for me. I didn't have to return the defective shoes so I was thinking about trying to fix them and use them for my indoor trainer shoe.

Anyone know what I can use to bond the sole back to the upper leather? Anyone have success doing this?
