I had plantar fasciitis and ankle issues galore. Was running in size 12.5 Saucony Triumph 18 I think, maybe 8mm drop, don't know.
Got some Altras size 13 and my injuries went away. I think it's because of the wide toe box giving my feet room to spread out.
The zero drop of the shoe perhaps helped my ankle. It doesn't hurt and I can run without pain.
I guess people who like Altras like the alot. I'm one of those people. Bought pairs to work in, and walk around in. They feel like slippers, so comfortable.
