The Flying Eagle F7 Optimum (Dual Density) is the most advanced rigid skate in the world of inline skating, combining different densities of plastic getting the perfect support and flexibility for all styles of urban skating.
The F7 has softer plastic sections like the back of the cuff and in the area of the laces, designed to keep the skate comfortably tight on your instep, at the same time. Excellent for jumps. The ankle is firmly held in a comfortable way but with the freedom to move in a forward and backward movement. This quality is important for long distance skating, as it allows you to bend your knees forward more than usual.
