Those boots are two weeks old!? Well I bet your blisters come from the bashing around and not the boot fit. No matter the environment the boots should fit well and not cause any blisters. Do alternate your boots every other day too. You do seem to get your boots to work! Enjoy them in good health and you certainly seem productive. Best wishes for your success. Seems some conditioning weekly and brushing daily would go a long way to prolonging their life. Enjoy!
