Woodland — Shoe makes a creaking sound

I bought a pair of woodland shoes 2 years ago from Vellore. They are very comfortable but they have been making a loud creaking sound in the right shoe while walking. This is particularly loud in cold weather in a place like Kotagiri where I am stationed now. The issue appears to be much lesser in warm weather. It seems that the sole of the shoe or inner part is getting hardened in cold weather and is making the sound which is quite embarassing. Is it possible to get it repaired in a place close to Kotagiri or in Chennai?
