Have a good friend living overseas who has to spend a fortune to invest in new running shoes and he does run lots of kms.
Read conversation before about "running goo". My question - what does it do and how is it used? Does it breathe old life into the soles and help the runner to get a bit more distance out of the soles before he has to get a new pair of shoes?
In other words - is it worth me sending a tube of the stuff to him ever so often?
