I purchased these about two years ago and used them for six months, but I no longer have the opportunity to wear them, so I'm selling them. Sold out on the site. They have good cushioning, so I think they wouldn't be stressful to wear for long periods of walking. I usually wear a size 22-23cm, but I remember they felt a little big. Heel is about 6cm. ⋆┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈⋆ ⚠︎Please check my profile before purchasing. ⚠︎Please refrain from purchasing if you are sensitive to items being handled by a non-professional. ⋆┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈⋆ SHEIN Shein Ryousangata (Mass Produced)
