Bottom line

On aesthetics, the Sidi Defender 20 looks quite unique compared to its Sidi siblings. However, consumers who assume this pair is all there is would be missing out on its excellent comfort, efficiency, and versatility. It is being used for all types of leisurely rides on the road and mountains.

With all that said, its reportedly subpar materials have turned some individuals off. All things considered, the shoe's practical features and relatively affordable cost that delivers on the bike may satisfy your preferences.

Updates from its predecessor

The Sidi Defender 20 is a low-top version of its sibling called the Sidi Defender. Both shoes are developed with almost the same features for identical purposes. Below are the two shoes' differences:

  • The older Defender features a mid-profile medial collar. It serves as ankle protection from bike bumps.
  • The newer Defender 20 got rid of the micro-Velcro strap and settled with just the Tecno-3 system for its closure mechanism.
