The Forma Simo Ladies Leather Motorcycle Boots Black (Euro Size 39) are packed with features... Excellent, barely used condition. Some scuffing from foot pegs (see photos). Had foot surgery and these no longer fit. Designed for women, this handsome Italian-styled touring boot features a waterproof, breathable membrane, ankle and shin armhe heel. The Simo boots include flexible panels on the top and rear of the ankles, plus dual-flex nylon midsoles that offer flexibility in the front while maintaining stiffness in the heel. If you’ve ever had to walk around in a stiff racing boot, you’ll appreciate this flex feature. What Forma calls its APS (Air Pump System) is really just a thin footbed insert. Shaped with a bump in the middle of the foot near the arch, the APS acts like a plunger as you walk. When you step, your foot pushes down on this bump, forcing the hot air out. When pressure is released, new air fills the bump. The shape is ergonomically comfortable, and even after hours of walking in this boot, my feet were no worse for the wear.
