That was why I was skeptical about being sized at a 15 1/2 when I've worn a 14 since high school. my thinking is the boots are too long and the natural bend point of the 15 1/2 boot is further forward than it would be if they were shorter. I went to the shop because I figured I could eliminate any errors on my part doing the outlines and measurements myself. In regards to the boot care, what is a better interval than what I've been doing. My thoughts were during the break in, treat the boots a little more often then once broke in about once a month roughly. Thoughts?
I have heard of other people being put in the wrong sized boots by retailers and White's themselves. They have a bias in fitting people into longer footwear than necessary because a little too long is much better than a little too short. An inch in front of the toes is not a problem if everything else is right about the fit, but it sounds like they aren't working right for you.
I am no expert on foot care, so please don't place to much faith in it. It is based on my experience and what the boot makers, including White's, say.
First, boots should promptly (daily) have mud and dirt wiped off of them with a damp cloth. Mud sucks the oils out of the leather. Dirt/sand can cause friction in seams between leather and creases, which will break down the leather.
If the mud is already dried, you can try brushing off some of it first with a horse hair brush. If a damp cloth isn't enough, don't be afraid to use more water and potential a very mild soap to clean them. However, if the boots aren't dirty, don't do this. Within reason, you can't brush boots too much. Then, you can condition your boots with a product such as Lexol or Bickmore 4. Washing the boots thoroughly will remove some of the natural oils, so the more often you have to wash them, the more often you will use Lexol or Bick 4. Also, dry weather can really damage leather, so you will want to condition them whenever you perceive the leather to be noticeably dry. Other than heavy washing and super dry weather, you wouldn't want to condition the boots more often a couple times a year, though a few extra times at the beginning to help with breaking them in isn't a big deal.
It also is very good for boots to dry thoroughly between wearing them. This can mean alternating between pairs of boots. You should never dry your boots in an oven or next to a heater. Some people advise using an oven on low for drying a boot or applying Obenaufs, but I think you risk harming the leather more than you help them. If your boots are regularly getting wet and you need to wear them again soon, White's and most other quality bootmakers advised buying an approx. $40 boot dryer from Peet. This will safely dry your boots overnight. Shoe (or boot) trees can also help, but they don't absorb massive amounts of moisture, just small amounts.
Obenauf's Heavy Duty LP is a great product, and is recommended by most quality bookmakers, but it will darken leather considerably. It also isn't necessary unless you are wearing your boots in extreme conditions: very muddy/wet conditions, very dry conditions, or exposing them to nasty chemicals. How often it will be used will depend on where you wear your boots.
Although I am just passing on hearsay, some experts on the Shoe Care thread on this forum, advise against using any conditioners with petroleum products or silicone in them. This includes Venetian Shoe Cream, so avoid that, despite what many will say. At the very least, it costs a lot more than Lexol or Bickmore 4 and there isn't convincing evidence it is better. Due their price, Lexol, Bickmore 4, and Obenauf's are really the go-to products. People also speak highly of Huberd's Shoe Grease, which I believe is relatively equivalent to Obenauf's, but I might be wrong.
So, in conclusion, there is no fixed way to say how often is too often or how rarely is too rarely for treating your boots, but know that most guys either never treat their boots, which is too rarely, or over-treat their boots. Very few just treat them when the leather obviously needs it. However, everybody agrees that you need to get the mud and dirt off them promptly and that you can't go wrong with brushing.
I find the FAQ on the website for Nick's Boots is excellent and covers these topics too. Nick's makes a product that has a lot in common with White's, so the advice is fairly interchangeable:
