I really love these shoes! They are so soft and cushy. I purchased the black pair first. I wore them everyday since I got them. My thought when purchasing was I would just wear them just around the house and in the yard to wash the car or for gardening. After putting them on I didn’t want to wear any thing else! I’m usually an avid Birkenstock wearer. I have 9 pairs of Birkenstocks. These rubber Birkenstock look a-likes DO have arch support. Maybe not as high of an arch as Birk’s, but, enough where my feet don’t feel unsupported. I ended up wearing these shoes out running errands too! I ended up purchasing the white pair to wear with lighter color clothing too. The white pair was a little bit bigger in size. Even though both pairs are a women’s 9-10. (I usually wear a size 10, sometimes 9.5 in sandals) The mark on the bottom of the shoes say M 255-260. Euro sizing? The sizing on the white pair wasn’t that far off, so I kept them. On both pairs I made more holes with a shoe/belt leather hole punch on the straps so I could make them tighter. If I hadn’t made more holes they would have fallen off my feet. Being able to tighten the straps down more made them fit perfectly. I have plenty of room for my toes to splay. The shoes do NOT make that poot sound other reviews have spoken of. I thought if they did I would make holes with the leather punch on the sides for the air to escape. But, no need. Once in awhile, especially if it’s hot the shoes will rub on the inside part of my foot against the shoe. I will put a little Aquaphor or baby powder on my foot in that spot so the shoes will glide over that spot and not stick and form a blister. As, I do wear these barefoot. If it’s really hot your feet can sweat inside these. In that case, I will use some powder on my feet. I love how easy they are to kick off and then put back on again. I might wear socks in the winter with them. Who knows! I love that I can just wipe these shoes down with a Clorox wipe. Then, I’m good to go! I did have to trim off some of the extra rubber that was left behind from manufacturing. The white pair had loads of extra rubber that should’ve been cut off. It was no big deal to trim it off though. I would definitely purchase again. Especially if they got the navy blue back in stock! Get them! You won’t be sorry!
