What if the boots have already been treated with Sno-Seal? Impossible to use Hydrobloc, or must one wait for a season for it to wear off, etc?
Well- wax-based treatments are very effective at repelling water, so I would expect it to be difficult to get a water-based treatment to penetrate...
The good news- or the bad news- is that wax-based treatments don't penetrate deeply into the leather, so one should be able to apply a water-based product once you have put on some miles.
I tried using wax-based products on my logging boots back in the mid-90s while logging on the West Coast. I stopped because wax-based products may water-proof leather, but they don't condition and maintain leather- at all. Flex points, and points of wear, abrasion, will soon split and crack.
More bad news about wax-based treatments- they prevent glues from bonding. In 1995 I tried to resole a $500 pair of faller's boots in Vancouver- the cobbler told me that he could not as he would never be able to remove enough wax to get the glues to bond!
I have since gotten correspondence from a number of leather-boot manufacturers that have confirmed this issue with resoling boots (e.g. Scarpa, Andrew, Crispi)- if you think you are going to eventually resole your boots, don't use a wax-based leather treatment.
