I have wide size 6 feet and jump around in group exercise classes. I love the give with the mesh for my wide forefoot, with all that lateral movement. The color is great, if you don't mind looking a bit metallic. Toned down from the usual "bright white" cross-trainer effect. This is lightweight and has wonderful cushion for my plantar fasciitis. Although, I still put gel heel inserts in them to avoid heel pain. I ordered 6D (wide) and they're great. Usually, the B-width is okay for me with just a little stretching. From multiple reviews, I get the impression that ASICS sizing can be inconsistent.
