Hurts
Size: 7.5, Color: Orange Patent
They’re like way more neon than I thought they’d be. They also are not comfy like at all so…I’m returning them .

Uncomfortable
Size: 7.5, Color: Orange Patent
These would have been perfect, but the toe separator is way too hard. I tried it on and it was painful before even walking. I expected better quality from Steve Madden 😕

The best but SIZE UP!!!
Size: 6.5, Color: Silver Leather
These are my new favorite heels I own. Soooo cute, survived being rained on at a beach wedding (and were surprisingly decent to walk on in the sand if you're confident in heels), and aren't too uncomfy even though I have super high arches. I'd advise people to size up though, esp if you have wide feet or high arches. I usually wear a 6-6.5 and had to switch out 6.5s for 7s (and if I didn't prefer a snug fit I probably could've even gone with 7.5s). Overall these shoes are so beautiful, versatile, and seem like they'll last long. A tiny bit slippy (and would recommend anti-chafe where the straps will land if you're blister-prone) but not a biggie
