A 78A durometer street-shaped wheel sounds like an excellent choice for cruising or filming due to its softness, which provides a smooth ride and absorbs vibrations from rough surfaces. The dimensions of 34mm x 18mm suggest a compact size, likely providing agility and maneuverability while still maintaining stability. Additionally, the emphasis on silence implies that these wheels minimize noise, enhancing the overall cruising experience. Overall, these wheels seem well-suited for urban commuting or capturing skateboarding footage without disturbances.
