I used to get all my running shoes from Nike, the Pegasus line which was always their basic running shoe that was very good overall. These days, I can get what is basically the same shoe from Decathlon for 1/5th the price of last year's Pegasus.

Running shoe tech is not some kind of secret thing. Any shoe manufacturer can buy a pair of any other shoes and cut it open and copy it. The only shoes that have anything special in them are the ones with the carbon fiber spring plate, and those are highly specialized and only last for a few races anyway, not for me as a casual runner in his 40s.
