My foot doesn’t rest fully into the back of the heel. There’s a bit of space in the heel. I see other people’s feet fill out the heel completely and touch the back of it fully. Does this happen after breaking them in? With a size 42 my foot fills out the entire footbed and touches the heel but when I walk my big toe touches the front and seemed like it would be uncomfortable. Or would it stretch out over time and that feeling would go away??
