Perhaps this has been covered before. Has anyone used Trials boots instead of conventional MX boots? My old Alpinestars will need to be replaced soon, I would like to get something that provides more traction when pushing/ walking. I just don't want something with an aggressive lug sole that tries to "grab" every clump of dirt. Has anyone modified a sole to get more foot traction and maintain the boot's ability to "skim over" the dirt, sticks, rocks, etc? Thanks, Jim.
