I live in Malaysia and bought the boots in San Francisco. Had the shoes since Feb 2012 and worn i think bout 30-40 times since then. Cleaned the boots once with Obernauf cleaner and used the RedWing conditioner after that. I applied 1 coat letting it absorb over night and then another light coat the next day. That was bout 2 weeks ago. Worn the boots twice since then and today i found this. Should i be worried? This is the right side. The left side shows sign or starting to crack.
