The only constant in the running shoe business is change. A shoe model’s life is about 12 to 18 months. Once you find a model that works for you, it will no longer be available.
Since a shoe’s midsole’s effective life, being used or sitting on a shelf, is less than two years, it does not help to buy multiple pairs of the same model to use over many future years.
Since November 2021, a model that has worked for me is the Saucony Triumph 19. I’ve used two pairs for 642 and 682 miles. Other than the original Nike Vomero 1, the 19s have been my most comfortable shoe, using them for more miles than I should have,
When replacing the second pair, I bought a pair of Saucony Triumph 20 in mid-February 2023. Since then, I have logged 43 miles, with my longest run of 11 miles.
I intend to use these shoes three days and 23 to 32 miles per week. I’ll use them for my long training runs and races.
They are cushioned neutral shoes with a semi-curved last. They are heavier with an offsetting bounce,
They meet my primary need of a flexible shoe. To help with pronation, I need a shoe that bends where the toe meets the heel.
There is no visual sight of posting in the shoe, and they are advertised with no posting. The 20 appears to have the same mid and outsole as the 19.
The upper is still one piece. Flat rather than cord laces are used.
