I also compared these to my Alti 160mm. BUT JUST A NOTE!! My Altis are 35.5. So it IS a little smaller. Pitch is about the same, heel height is JUST a smidgen taller on the Maggie (proportionate to size). The platform on the Maggie, makes it more comfy to walk in than the Alti.
When it comes to the toe box, the Maggies are a lot roomier. Even if I half sized down in the Maggie, my toes would be more comfortable than in the Alti.
The Maggie 160mm runs TRUE TO SIZE. I do have a somewhat narrow heel, however once I slip in the Heel Petalz, it was perfect!! So for those of you with average feet, definitely go TTS!!
