Ride 14 Runshield

I'd agree with the sentiment that if it's seriously raining, waterproof shoes won't keep the rain out and if anything won't drain as well, at which point I just embrace the wet, heavy feet and prioritize faster-drying meshy shoes. That said, I own Goretex shoes (currently the Nike Pegasus Trail 4 GTX) and the Ride 14 Runshield (part of Saucony's winterized, water-resistant series), and do find they work well for drizzles / puddles / generally better traction, as well as added warmth for winter.

How about Brooks Ghost or Saucony Ride? Both are about 7mm more than the Kinvara, so that probably qualifies as "a bit more" that you are looking for. These classics are going strong and are on their 17th and 18th iteration for a reason. I think this subreddit is so focused on the latest trends that commenters forget that these classics continue to exist and sell in huge numbers for a reason. Also, I'm not sure if you want low stack or firm - it's not necessarily the same thing! For example, On Cloudmonster 2 is higher stack but much more firm than the aforementioned Ghost and Ride.

If you want something that lasts and is worth the money, look at the Saucony Ride or Guide series. Most "hyped" Running shoes use soft foams that bottom out after 200 miles, but Saucony tends to use slightly firmer, more resilient materials that hold their shape for a long time. Don't buy into the expensive carbon-plated trends yet; just get a solid daily trainer.
