I saw a thread about this a while ago but canât find it so sorry in advance (i swear the search function doesn't like me). Somebody on the thread talked about a product that put the natural oils back into the leather, softens the leather up + water proofs it. Just got a new pair off the RQ that need breaking in so may as well apply this stuff onto a fresh boot, they are for the field so Iâm not worried about getting a shine on them. Somebody else said ferrets wax? Any better/worse than the oil Iâm prattling on about? Edit to add - Found the post Iâm on about. Itâs indeed neatsfoot oil Iâm thinking about, softens the boots right up but adding too much makes the leather susceptible to cuts/tears and also can make the feet too warm in summer. Looks like itâs a case of only a layer or two instead of loads. Cheers OnFire.
