Following up on this, I ordered the Craghoppers Locke shoes and they arrived today. They are more substantial/weighty than I’d expected. That will improve their comfort I guess but just not quite as packable as I’d hoped. The hole you slip your foot into seems a wee bit narrow, even if the rest of the fit seems good (reviews indicate that I’m not the first to experience this). At full price, I’d have possibly returned them but I think they’re worth keeping and I might press them into service for packrafting too.
