Hey, many thanks. I'll give them a call and will report here in the end.
Yes they are that good that I use them for climbing too! Up to medium grades then switch to climbing shoes. Reason why I need to resole them after only 4 months of use. 3 times per week approx. So comfy they are that I walk with them, climb with them and back to the car with them too. Hate climbing shoes after finding out what TX4s are really like. Love them!
