Design a conceptual sneaker using a color palette primarily composed of red and gold. The sneaker design should be modern and stylish with a structured body shape and sleek lines. Incorporate striking gold accents for added flair against the predominantly red base. The materials should look high-end and luxurious, such as glossy patent leather and smooth velvet, suggesting quality and opulence. The shoe should appear as if it is constructed for both aesthetics and performance. Make sure to abstain from including any text or writing on the sneaker.
