Different shoes definitely have different grip properties but my experience is that the relationship between grip and contact patch isn't so straight forward.

The good analogy is tires. Perfectly slick tires have the largest contact area but will hydroplane/slip meaning less grip in the wet. I have a pair of soft soled racing flats which work brilliantly on the track but on the road in the wet they are pretty useless. Where they really suffer is in the corners and changing speed. This is makes it difficult to estimate the speed penalty as its extremely course dependent.

The issue with shoes like the ones you have picture is that they will pick up mud/dirt/rock/etc. even on the road in poor conditions. Not only does this increase the weight of the shoes but can impact traction. I have run in Mizuno shoes for many years and they do accumulate debris in the opening in the sole under the wrong conditions. The issues hasn't stopped me from continuing to buy them but trail shoes and/or cross country spikes don't have such large holes in the sole for a reason.

When I had Ons I def noticed they are very slippery, especially on new asphalt even if it wasn't entirely wet. So to answer your question about the shoe specifically - I didn't wear mine if it was wet unless it was grittier concrete or older rough asphalt.

I've never had issues slipping while pushing off in wet conditions with any shoes (many brands and even trail shoes on pavement) but I've never used anything that looks like what you pictured.

I'm not a coach or expert but I'm guessing the slippage is possibly from your running form. If you are pushing off hard and late, I'd guess this would be the cause more so than the shoes.

Could be down to the shoes. I run in Adidas Supernova/ Tempo with the continental outsole and they are wicked grippy on wet tarmac, at any speed.

Yeah, I have a pair of adidas (solar) with that Conti-Sole aswell. Considering using them in the future in wet conditions when it matters.
