Of course they're comfortable because they're from Corkys so they have the signature cushioned memory foam insole that will keep your feet happy all day long. The lightweight cork wedge is about 2.5" with a 0.75" platform which is just the right amount of height without being too tricky to walk in and giving plenty of support.
These fit true to size but only come in whole sizes. If you're between sizes, you'll want to size up.
