Okay so I go these in April (sister and I went halves as my birthday present) but wanted to give them a full winter season to review properly. They have certainly had a full winter season and they are amazing. So comfy, so easy to clean & dry, and so versatile! Well worth the purchase and they go with so many outfits. Worn them in the office at work, out for walks (most of my photos), into town on the weekends, with all different types of pants & jeans, and skirts and dresses ( no pictures but trust they looked really cute with A-line style and denim in particular). Every single wet day, I've built my outfit of choice around them... they are awesome! Can just mindlessly take them into any terrain and then wash em off with the garden hose or in the laundry tub if they get dirty (so good for winter muddy & wet parks everywhere).
I have high arches, narrow mid foot and wide toe box and they fit very comfortably. They are a smidge roomy for me in the vertical height (around toes and heels in particular) but I went up a size to a 10 from my usual 9-9.5 for the toe box width and room for thick socks (as they suggest too), which was a great call cause they still stay on fine and are comfy with thinner socks - but only wear long socks with them cause the neoprene lip can dig into your bare skin a little bit, on certain angles.
The Bobbi is a good all rounder cause the heel is low and still good for walks around parks / town, but I reckon I'll upgrade my always-too-narrow black…
