Sidi all the way. I did just like you, surgery with hardware in ankle.......and I wanted GOOD boots when I was ready to ride again. This was 10 years ago, still have same Sidi TA boots. They're not cheap, but very protective, totally waterproof, and I've got THOUSANDS of miles on em.........just do new toe guards and soles every 4-5 years. In my opinion, the Sidi's are head and shoulders above the boots you have listed. I've owned A-Stars and I don't think they even hold a candle.
