how thick are the soles?

They are pretty thick in comparison to "Vibram" or other functional toe shoes that are out on the market. You get way more support.

I am a female. I ware a w 9.5 what size should I order?

Hi This is the size Chart of barefoot shoes. US 8 Women/6.5 Men; US 8.5 Women/7 Men; US 9 Women/ 8 Men; US 10 Women/8.5 Men; US 10.5 Women/9.5 Men. I recommend you to order size 8.5. If your feet are wide, shoes made of fabric will suit you better.The Wide toe box provides more space for toes for more comfort. You can choose the size according to the size table and other customers' answers. If you have other questions, you can contact the seller's service.

Is the fidget spinner on the bottom included?

Looks like fidget spinners but non functional.. just a design pattern in the sole

I wear a size 46eu, or 30cm. what size do you recommend?

I am a size 12 (45 EU) and the size 12 fits me perfectly. For 46 EU, I'd go with the size12-1/2 - these shoes are very flexible and roomy and expand a bit over time. These are great shoes, but the soles don't last long on cement and are a bit thin for sharp, rocky terrain. They are ideal for grass and smooth dirt trails. I use them for outdoor volleyball and golf.
