To be honest, I was rather skeptical about the glue was concerned. Because I've tried quite a few over the years, unfortunately, often with little success. Because of the good reviews but then ordered. Applied as directed. And see what I did not think the shoes hold now already a couple of weeks. And that with a twelve year old boy who still like to play football with the shoes at school. Am positively surprised. Would thoroughly recommend the adhesive. But as I said, observe statement.
