Very wide in the heel. I had to purchase toggles to get the elastic tight enough. Good toe room but at the expense of too wide of heels. Comfortable. Great for quick trips to the store.
Update: Bought toggles so I could tighten them. They seem to get larger (as in stretch out) each time I wear them. Cushioning does not "spring" back. Doctor says they do not offer any form of support. I agree.
I would not recommend for anyone with knee problems or ankle problems such as I have due to the stretching issue.
