Those properties are mostly mutually exclusive.
Shimano sandals are comfy to walk in, almost like reg. shoes. They flex a lot. They are heavier than my mtb shoes, and a lot heavier than even cheap road shoes.
When (early 2005) I got the shim sandals i also got some exustars and lakes in same size, then took them to the usps and weighed them. The Shim had a slight weight advantage, but they were all pretty heavy for cycling shoes. Shim were the best fitting of the lot for my feet.
I rode my sandals all summer, then put on my mtb shoes in fall. The increased rigidity of the mtb shoes immediately increased my average speed for identical route by 1 mph, which is significant when you average 12mph. So, you waste energy when riding flexy shoes.
IMO the best solution is a pair of comfy, light road shoes for on bike, other shoes for off bike.
I'll also mention that one of the most experienced bicycle tourists / forum members rides in light backpacking boots - not even the low rise version - and these are apparently his only shoes on tour.
