Looking to grab a new pair of heels, and I like the Sidi ST sports up against the Alpine* supertech R. Who's had experience with these boots? Your thoughts appreciated. Feel free to recommend others. Riding style is fairly spirited, in all conditions, long distance and short. And yes do have to do short spells of walking in them *Important Point* My right leg has injuries, so getting in and out of boots is difficult. As such full zippers are a must, no slip-ons.They need to have plenty of ankle access/flex, or be able to spread at the front and rear.
