Is the Ryka Generation good for narrow feet?

Yes. It is offered in narrow widths, and the women-specific last runs snug through the midfoot. Walkers with average or wide feet should size up or look at a wider Ryka model.

What is the heel-to-toe drop?

12 mm. That is a high drop, which puts more of the stride on the heel and suits casual walking more than forefoot running.

Does it have a removable insole?

It uses an Ortholite insole over EVA. Ortholite insoles are typically removable, so you can swap in your own orthotics, though the fit may change.

No. There is no Gore-Tex membrane. The mesh and faux-leather upper breathes well but will soak through in rain.

What sizes are available?

Listings run from US 5 to 11 in half sizes, in narrow width. Check the specific colorway, since not every size is stocked in every color.

How does the Ryka Generation compare with the Ryka Devotion?

The Generation is a lighter, lower-profile walking shoe with a 12 mm drop and a mesh upper. The Devotion line is a plusher, more heavily cushioned trainer, so the Generation suits casual walks and the Devotion suits longer standing and walking days.
