For anyone that hasn’t worn Dansko, try them. Initially they can be awkward. You’ll instinctively want to hold on to the front footbed with your toes and try to keep the heel on without the up and down movement of the heel. Don’t. It’s a clog and even though the XP 2.0 is a “full shoe” it’s still a clog and should be walked in them that way. Relax your foot, don’t squeeze your toes to hold on and let the heel “flop” like a clog.The XP 2.0 is amazingly lightweight. Much more so than any others I’ve worn including all of the cute dress shoes. Plus they come in so many fun colors and patterns.I have problems with my pinkie toes and calluses on my heals. When I started a new job that requires 8+ hours on concrete flooring, I knew it was a time for a new pair of Dansko. I still have tons of dress shoes by Dansko but knew they wouldn’t work. I saw great reviews for the new Professional XP 2.0 and decided to try them. I was skeptical about the sizing based on other reviews. In the past I wore a 36 (regular size 6.5). However, I decided to try the 37 because I’d be wearing my new pair with socks. Great idea if I do say so myself.I feel like they are a little too loose in the back but they are perfect otherwise. I have a narrow foot but always wear a medium. These are a tad loose on the sides as well but with the socks they are perfect. Question: should they fit perfect without a sock? If so, mine are too big. With socks my heels are a pinky width too loose (recommended) but the front is perfect. Being a pinky width is what I’ve read is the true fit.Mine were broken in three to four days after receipt but I can’t get the top to loosen up. It’s not painful but irritating because the rest of the clog is perfect. The toe bed, the arch support, everything is exactly what it should be for me except the stubborn top across the center. Does anyone have an idea of how to stretch it? I’d also love to have someone confirm mine truly are the best size. I’m worried the 37 might be too big but I’m more concerned the 36 would be too small. The 37 states it’s a 6.5-7 US shoe size. Some reviews say size up and some down. I plan to keep my 37s but may try the 36 next time when I buy a pair in another fun pattern.All I can say in the end is trust yourself, buy the size that fits your US size and they’ll probably be the right fit (a little loose for the 6.5 but probably perfect for a US 7 both in 37 in EU size).I love mine and will keep buying them as long as Dansko keeps coming up with more comfort and cute, colorful patters. Thank you Dansko!
