In Japanese, sayonara means goodbye and it was sayonara to the Miuzno Wave Precision & Elxir and konnichiwa to the replacement model called the Mizuno Wave Sayonara
. The shoe caters to neutral runners and is 1.5 ounces lighter than the Precision and an ounce lighter than the Elixir.
I've been amazed at the reduction in shoe weight over the last couple of years and the Sayonara is using a new midsole foam called U4ic, which Mizuno claims is 30% lighter, softer and just as durable. The Mizuno Sayonara hits the scales at 7.9 ounces in a size 9. The heel is 24mm, forefoot 14mm, for a drop of 10mm.
