Is $71.99 a good price for these?

Yes. That is near the low end of the recent $69.99 to $76.49 range, and well under typical retail for a leather Cole Haan oxford.

How do the Original Grand Wingtips fit?

They generally fit true to size, but some buyers with wider feet go up a half size or choose the wide width. Try them on with the socks you plan to wear.

Can I wear these with a suit?

For business casual and softer suits, yes. For formal or conservative settings, a sleeker leather-soled oxford is the safer choice.

Are they good for standing or walking all day?

Yes. The EVA midsole and rubber outsole make them far more comfortable than a traditional dress shoe, which is their main selling point.

What widths and sizes are available?

Medium and wide widths, in US sizes 7 to 16, including half sizes through 11.5.

How should I care for the leather?

Wipe them down, use shoe trees to limit creasing, and condition the leather occasionally. Avoid heavy rain, since the perforations are not waterproof.
