So leather needs to be kept at the right level of hydration. If it gets too low, the leather can be irreversibly damaged. It will get stiff, and will be prone to cracking when flexed. If shoes are stored at too low a humidity and the moisture is not restored, then stiffness and cracking would be expected.
Since I moved to Western Montana - we do not have as much humidity, partly because of the Rocky Mountain air and elevation. Do you have web links or suggestions as to what would be best for me?
To date, my shoes have not cracked - but knowing how and where to store them based on my location would be extremely helpful.
All my best,
