These replaceable heel pads add extra life to SIDI shoes. They're easy to replace and relatively inexpensive from BTD. I usually keep a couple of extra pair on hand so I'll have them when I need them.
This rating is probably confused with a general rating of my Sidi shoes. The Sidi design allows for replacement of any parts as they wear to extend the lifetime of their shoes. This design has kept my old Sidis going for 10 years. I do replace the heel pads once or twice a year. Straps and buckles also are replaceable and I occasionally replace the straps, heel pads and cleats to refresh the shoes.
After years years of riding the old black shoens I finally purchased a new pair of Sidi white shoes for summer last year. Still the fully maintainable, interchangeable design. The old shoes are now relegated to winter riding.
It's wonderful to be able to replace worn parts as opposed to buying new shoes! Don't wait like I did so they are so worn you have to drill out the old screws.
The Sidi heel pad wears out far too quickly. This is a Sidi issue. But if you use Sidi shoes, you have no choice. Bike Tires Direct has the best price - I've seen the pads from other retailers for more than twice the price. Go with Bike TIres Direct.
