I highly recommend! These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.
