I recommend Saucony Grid Stabil 6 daily for narrow feet needing a lot of support. This year Grid Stabil was replaced with Progrid Stabil as Saucony’s ultimate support shoe. Unfortunately, Progrid Stabil is nothing like Grid Stabil and if you wear this shoe, you may be headed for injury if these differences matter to your foot type. Here are the major differences.
- As the image shows below, ProGrid Stabil is flexible whereas the Grid Stabil is not. Rigidity is important if you pronate excessively or have forefoot pain.

- Medial Midsole – The Grid Stabil has a firm medial midsole whereas the ProGrid Stabil has a less firm (softer EVA) midsole. If you are a heavy pronator, you need a firm medial midsole.
- Deeper Upper – The ProGrid Stabil has more more mesh, is wider and has a deeper uppr than the Grid Stabil, making the shoe much wider overall. This is not good if you have a narrow foot and will cause your forefoot to move side to side motion more, which may cause pain.

- Flex Grooves – The Progrid Stabil has an additional flex groove which create more forefoot flexiblity. One of the reasons I like the Grid Stabil isthat it doesn’t flex in the forefoot. The same cannot be said of the Progrid Stabil. The Grid Stabil is also narrower overall than the Progrid Stabil.

In summary, the Progrid Stabil is not the same as the Grid Stabil. It’s wider, deeper and less stable. If you have a narrow foot and you need firm medial support and an inflexible forefoot, then the Brooks Addiction is a better choice than the new ProGrid Stabil. If you have a medium foot, then Saucony Guide is a much more stable shoe.
