Insole

I bought a insole today. The reason why I bought it was that I had a ache at back of heel in new climbing boots. I hoped to reduce the ache by support of insole.
I brought the boots to the shop. And the clerk proffesional helped me to select the best size of it and cut the edge in order to fit to my boots and my feet. The sole fit to my feet especially at my arch of feet.
And I had a trouble at my knee when I walk for a long distance. But I heard that the sole would help me at the problem.
I will check the talent of the sole in mountain.
