Extra Butter and ASICS collaborated to create a collection of shoes inspired by Kill Bill Vol. 1's Deadly Viper Assassination Squad, ten years after the film's release in 2003. One of the sneakers from this series is the Gel Epirus 'California Mountain Snake', which draws inspiration from the character Elle Driver portrayed by Daryl Hannah. This sneaker showcases a color palette reminiscent of nurse uniforms and incorporates snakeskin details. The cushioning is designed with red spatters for added support and it is completed with a tri-color tread. The release of this shoe took place in December 2013.
