(This post is about clothing, but gear specifically - wasn't sure if this belonged in off-topic or not.) I've joined a running/walking group and have started training to walk a half marathon (!). We are starting with lower mileage and working our way up, but it's obvious that the longer distance weekend walks will be nicer if I improve some of what I'm wearing. I've got wicking socks and clothes, but most of it is a few years old now and the socks really need to be replaced.

Does anyone have any specific recommendations they have used and liked? With socks in particular I prefer a brand that comes in multiple sizes, because I'm a women's 10 and one size fits all socks are usually too tight. Would also love recs for fanny packs, water carriers, etc.
