Thank you for viewing. I'm selling these shoes because they didn't fit my feet, even though I wore them twice (20km) for speed training. - Brand: Brooks - Model: Hyperion Elite 3 - Color: Blue Surf / Cherry / Nightlife - Size: 27.5 - Condition: The soles are in good condition due to the short running distance, but there are some lint balls from socks on the inside of the heel, so I've marked them as "Slightly scratched or dirty." From the official website: A carbon plate model that combines speed and stability This speed model has evolved in fit and will lead you to a personal best. The upper, heel, and tongue gently wrap the foot while securely holding it in place, updated with comfortable fit and breathability. Midsole material: Uses "DNA FLASH," a lightweight and highly responsive material. By using a liquid forming process that fuses high-density liquid nitrogen into the material, it achieves excellent cushioning and high resilience while being ultra-lightweight. Efficient running energy: Enables you to continue running with an ideal form, creating room to persevere even in the latter half of the race. The combination of DNA FLASH, which achieves a lightweight and responsive running feel with soft cushioning, and Brooks' unique carbon plate enables even greater stability and speed. Enhanced fit: The shape of the heel, tongue, and upper have been redesigned, improving the fit and breathability compared to the previous model. New shoelace construction: Made from 100% recycled polyester. Designed to hold the foot securely in the right places, keeping your feet comfortable even during important races where you're aiming for a personal best.
