I have wide feet and love my Asics, I think they're Gecko, for trails. I wear NB for road shoes which aren't quite as comfy.
I have a LOT of running gear, from H&M to Decathlon to M&S and Sweaty Betty, as well as some sports brands such as Reebok, Asics, Adidas, XT, and Gap. I like them all for different purposes, but really rate Gap for tights, H&M as well, and XT for compression tights. My race jacket is Asics.
For cold weather 100% merino is the only choice for me. I get long sleeve tops from Decathlon, and also Mountain Warehouse. They are breathable and make a massive difference.
Bras are Nike, M&S or Uniqlo, I don''t have too much up front! I get annoyed when they have the removable pads in which always get twisted in the wash. Seamless knickers are Uniqlo or Decathlon own.
My socks are Asics or random makes. I have some fancier Hilly ones for longer distances.
I really want a cropped top that is semi decent that I can wear on its own when it is hot but apart from Lululemon which is £££ I can't find one.
In the summer I don't go out without my running headband (compress sport) and visor, and usually trail glasses as well.
I also spend the most on my running kit, I'm in it most days!
