Offering similar impact protection and design to the flagship Sidi Vortice, these brand-new Sidi ST race boots appear to ditch some of the fancier features in order to lower the price from $475 to $395.

Gone appears to be the Vortice’s micro-fit “Tecno” adjusters that tighten cords around ratchets in order to offer precise adjustments. Instead there’s an Alpinestars-style ratchet strap to close the boot at the top. Also absent is Sidi’s trademark foot bridge strap that’s designed to restrain the foot within the boot so it doesn’t slip forward under impacts, crushing the toes.

Retained from Vortice to ST are the impact-absorbing external heal cup, the polygonal ankle hinges that limit the degree to which the ankle can flex or extend and provide impact protection and the Vortice’s “easy entry system” that sees a large part of the boot’s upper peel back to facilitate putting them on. There's no further images of the ST available, but presumably that entry system will look just like this.

Both perforated and non-perforated versions of the boot will be on offer with colors including black, black/white, black/blue or black/red. Motonation, Sidi’s American importer, says the boots themselves and more details on them will be available here in December.
