These shoes are great. They have a larger toe box than the Kelli Pro--so I needed a size smaller and I love both pairs (size 40 Dylan boots and 41 for shoes). The soles are exactly the same, it's the construction of the upper shoes that are different. Both pairs work really well supporting my feet with plenty of room and they are wonderful for walking around the cement streets of NYC all day. Plus the fact that the soles are flexible and lower to the ground so they feel very different from clogs in that way. When I worked in a hospital I lived in clogs but found them uncomfortable in many other situations-- stairs, city streets, subway platforms, museums. These feel like the clogs I loved while being better in my new endeavors; they are quieter and feel more secure. I recommend them highly.
