Very stiff sneaker however I did not read up on the details about it. This sneaker is a platform high heel sneaker inside so I can understand the stiff fitting necessary for support. I love the velcro straps which make easy for fast slip on and off. This is not sport sneaker and if you like a little height then go for it. Overall I wear heels anyway so these sneaker are comfortable. Like I said make sure to read the description. Happy about the purchase.
