I need shoe advice. I'm starting to train for a 50 miler (90% asphault) and I want to get another pair of shoes. Currently I'm using a pair of Saucony Triumph 11s (about 250 miles) and they're ok I plan on using both until the triumphs die. Before them I had always used Saucony Kinvara's and I liked them a lot more but I figured that I should get something with some more cushions for runs over a couple hours. I like that the Triumphs are still somewhat light but my feet end up hurting in them after a little while so I feel like they're heavier than I want without having more cushion.
So, what are some good shoes to look into? Can I just use Kinvaras and hope that my feet get stronger or is that just asking to get injured? There are a couple running shops near me that I may go to but there are normally just college runners working there so idk how much they'll know for ultras especially with ultras not being popular around me.
Thanks for any advice!
