Not sure whether to put in the beginners forum, as I don't know that much about shoes, or here.
Since I started running, I've solely used some Nike Lunarglide 6 that fit me quite well and seem an all-purpose mild stability shoe that works well for me. These will probably reach end of life in about two months, and it will likely be hard to source more in my size as it's an old model. I am a mild overpronator but appreciate a lighweight shoe. I'm also usually running distances between 8.5 and 19k at the moment, aspiring to a HM in October. I am not sure whether I should go for an all-purpose shoe or a couple of different ones to suit different distances. There are some very good deals on the Saucony Fastwitch 8 at the moment, but I'm wondering if this is viewed as solid enough up to an HM distance or not?
