You bet. This week I switched from Mizuno Wave Fortis to Wave Rider (simply because I couldn't find Fortis in shops for months), and my right foot began to hurt after only 20 km, though they're supposedly nearly identical shoes from the same make. I'll have to very gradually switch, alternating shoes between short runs, or maybe even give up the Rider entirely...
