After much social media teasing, Ronnie Fieg has announced the details for his Kith Aspen sneaker releases. The Kith x Adidas Ultra Boost Mid and Response Trail Boost designs will both release on Friday, Dec. 23 at all Kith stores at $220 and $160, respectively. The sneakers will release online at midnight EST on Dec. 23 via Kith. Based on sneaker release date calendars of boutique retailers, these styles will also release at Consortium accounts a week later.

The Ultra Boost Mid in the pack is a completely new silhouette that Fieg developed with Adidas at the brand's headquarters in Herzogenaurach, Germany. The shoe sheds the traditional cage of the Ultra Boost while extending its height and donning a multicolor Primeknit pattern.

According to Kith, the Ultra Boost style also uses a wool-blend Primeknit that retains warmth better than traditional Primeknit.

Both of these styles are part of Fieg's Kith Aspen program, a wide-ranging collection of winter-ready gear manifesting in Aspen with a special Kith pop-up.
