I'd like to hear from folks who have been wearing the Sidi Adventure boot. I have been trying it on and like the feel. however, when I sat on the bike, the sole felt so stiff, it was difficult to upshift. . It feels as though I need a full foot under the shifter, rather than just the toes. I do sport touring kind of riding where I need quick upshifts. the hope is that the boot should soften over time with the toe flexion. does this happen? What's your experience?
