Hi Quent,
I own multiple Lowas. They make a great boot, but their lasts may or may not create the best boot fitment for you. Keep an open mind RE other manufacturers/models.
Forget "getting it right the first time" by ordering on line.
Ordering serious backcountry boots by simply relying on the size stated is probably not one of the wisest decisions you can make. You may be able to get away with this for lightweight gym shoes or cheap dress shoes; however, high quality/stiff hiking boots are an entirely different animal (pun intended). It would be naïve to think you can order this type of footgear unseen/untried and expect the best fit in one shot. Hell, guys spend hours in stores trying on actual boots before finding the "perfect" fit, only to sometimes still be disappointed with their formerly "perfect" boots after putting real miles on them. Finding perfect boots is worse than dating for God's sake... and there is no upside to it.
1) Every human has a unique foot shape *and* expectations for boot fitment. What one man finds to be his perfect fit will be another's torture. This is even true between top quality boot brands/models.
2) The size printed on a boot is simply an approximate guide at best, because:
a) ALL manufacturers have their own boot lasts (forms/shapes)... this can differ substantially even between models of boots within one manufacturer.
b) Your feet may swell in hot weather or after miles of hiking. Thus, a boot that fits when you're rested and cool may be a blister maker once you're hot and exhausted.
3) I guarantee you that plenty of Rokslide members have boots gathering dust in closets that just don't fit as well as others, despite trying on those actual boots in the store. I sure do. AND, I have boots that are different sizes from different maker that fit me.
4) I also guarantee you a lot of Roksliders who will encourage you NOT to waste your time with mail order. That is, unless you want to pay for and order in a bunch of different makes/models and a range of sizes so you can have your own fitment day at your house. Then return the rest.
If you truly want the best shot at getting good fit from the get-go. Then, from the land of "do as I say, not as I do...", why not consider getting in touch with Lathrop? You can send them tracings of your feet and let them help you. Yes, you will pay for the boot. But, you will literally save hours of time and hassle. Or, you could post a wanted ad on the forum looking for used boots that don't fit other Roksliders ;-) I bet you'd have a TON of responses!
Seriously though, figure out how to get to a couple of decent stores and try a bunch of boots from different manufacturers or reach out to Lathrop. Be sure to bring your light/medium and heavy hiking socks.
***REALIZE THAT YOUR BEST BOOT MIGHT NOT FEEL THAT WAY AS SOON AS YOU PUT IT ON***
Serious boots can be seriously stiff out of the box. Thus, they will not begin to lace up/tension properly until broken in.
Feel free to pm me w/questions
Best,
