Seein' how the temps dipped into the lower 60's yesterday, I can appreciate your concern for you feet.
Hope that's as bad as it gets in the Shenandoah Valley this year.
I'm a cold weather lightweight. I will not tolerate riding uncomfortable. If I need to hold up 7-11's or ebay a body organ to stay warm, so be it. So far, I have never had cold feet issues on the KLR or on a Concours. A regular year round waterproof touring boot works just fine, commuting or long distance.
Here's a boot I bought a few years ago. They are my stompers, boots I can throw in the trunk for emergencies and forget about. What I like about them is that they don't have laces. Its a safety thing with me. Boot laces, spokes, chains turning at high RPM's, sprockets, loose boot lace......enough dots to connect to get a good picture yet? I don't want my next notice that I'm running low on good karma to be my leg getting wrapped around the swing arm.
Imagine. A KLR rider looking for a bargain on boots. If we ever get the Goodwill Coupon Swap up and running again.....in the mean time, you might find a price break here:
My shift lever is set up one notch on the shift shaft to accommodate my off road boots, so I have no clearance issues when shifting. Simple, DIY, and more advice available than would be wise to listen to.
