I currently wear knee/shin protectors with hiking boots.

I want to switch to MX or Trials boots with just knee guards. Do the boots interfere with knee guards? It appears from online pics the knee braces all extend down a bit and would overlap/interfere with the boots. I'm envisioning trouble standing up and down alot.

Please advise. Thanks.

I have Thor brand knee braces & Alpinestars MX boots. Yes, they overlap - but it isn't an issue. The top of the boot is big enough to encircle the brace (probably designed that way ) I also wear these boots with my leathers on the Motard track - no issues with that armour either, it also overlaps.

I don't know what trouble you might be envisioning as where they overlap is nowhere near where one's leg bends.

Any motocross boot I've seen or worn is intended to go over the bottom of the knee/shin guard.
Basically, the bottom half of the guard is covered by the boot, and the boot is designed to fit over it.
That's how it's done by me every weekend.
Just make sure you use motocross knee-shin guards with your motocross boots, and you won't have a problem.

I wear my knee guards with the bottom inside my boots too.

+2.. most knee protection is made to tuck in a little.. if it needs to. Your pants are over the knee guards, your boots are over the pants.. hard to put the knee guards over the boot..

So rydnseek, you put zip ties on a flat front tire and were able to ride?
