The wave plate in the Sayonara makes the back half of the shoe very rigid, with very Adidas Superstar Hombre little flexibility in any plane, but in particular it lacks torsional (twisting) and mediolateral flexibility. The heel counter really locks the back half of the foot in place. Why is this a problem for me? Here’s what I think.I’m usually a midfoot to mild heel striker in cushioned shoes, so I tend to land with either most of the outer edge of the shoe contacting, or at a point somewhere between the posterolateral corner of the heel and the midpoint of the arch. The problem with this is that I am contacting along the outer edge with essentially very little cushion between my foot and a big sheet of hard plastic, and this creates a fairly rigid lever that forces my foot to torque very rapidly at contact. You can see how close the plastic wave plate comes to the base of the midsole under the midfoot in the photo below – pretty darn close to where my center of pressure at contact is located (I had this measured earlier this year on a force treadmill).Mizuno Sayonara – note the grey plastic “wave plate” above the yellow cushion in the heel, also note how the wave plate approaches the bottom of the sole near the midfootMy Nike Air Max 2017 Dámské hypothesis is supported by what I feel running in the shoes – they feel jerky and slappy, not smooth. It’s kind of like what I’d image running in a dress shoe with a hard rubber heel would feel like. I can adapt my stride to make them more comfortable, but not sure I want to do that (more on this below).In contrast to the Sayonara, the NB 1400v2 is torsionally more flexible, and the sole is much softer under my contact zone. As such, when I contact the midsole compresses, there is a bit of flex, and the transition into pronation is much smoother and not as Adidas NMD Womens rapid. I feel none of the Sayonara induced jerkiness in the 1400, even though the sole dimensions are so similar.
As a way to compare the slappiness between the two shoes, I shot this quick video – listen to the difference in sound the two shoes make as a invert and evert my foot:So how Nike Air Max 1 Femme is it that the Sayonara can work so well for some people and not so well for me? As I stated at the outset, running strides vary highly from person to person, and I think this is a case where a shoe is just not a good match for my own stride. In fact, most Mizuno shoes with a wave plate Nike Air Max 90 Homme that I have tried feel clunky when I run in them. In contrast, Mizuno shoes like the Universe and those in the Evo collection (Cursoris, Ferus) have worked great for me since they lack a thick plastic waveplate like the one in the Sayonara. Sadly I’ve heard the Evo collection Nike Air Max 90 Mens is going away, so the Universe, Ekiden, and Hitogami (depends on how rigid the Hitogami wave plate is, the Musha and Ronin were iffy for me) may be my only workable Mizuno shoes going forward.
