Running in the rainy season

I picked up running this year and have really enjoyed it for the past couple of months.

I am curious to know from year-round outdoor runners: what is your essential wardrobe for Vancouver weather, especially regarding shoes? Is it advisable to buy Gore-Tex versions of the shoes that I currently own, like the Pegasus 41, Pegasus Trail 5, or Brooks 17? I read online that waterproof shoes are not always that helpful. I’m looking to hear the views of local runners.

Cheers!
