I have seen quicklime footbaths on the field. Technically they have the advantage to use a disinfectant which may be efficient in the presence of organic material (mud, litter, etc.) and thus may be useful weven when boots are not properly clean from organic material. Also, as opposed to liquid disinfectants, quicklime (as a powder) mays help reach a longer contact time, as it “sticks” to the boot. So, conceptually it could be interesting but so far there is too scarce available scientific evidence on their effectiveness. And the boots will have a shorter lifespan…
