Using the same weight, stack height and Smooth Speed Assist geometry of the original, the Mizuno Neo Vista 2 updates come in the form of materials and details. Over 70% of the knit upper is made from recycled materials, as is over 90% of the shoelace and sockliner lining. In the midsole, a Enerzy Nxt Eva Base and Nitrogen Infused Enerzy Nxt upper sandwich a glass fibre reinforced plate and are made in part with sugarcane-based biomaterial. This gives a fast feeling, energetic ride with a more sustainable approach to fast training. BLOOM (algae and seaweed-based product instead of oil based) is used within the tough and durable X10 rubber outsole for sustainable, long-lasting traction. To get the perfect fit Pro:Direct recommend buying a size smaller than your normal, or half a size if you have wide feet.
