What changes from the other listed sizes
The listings give this 8.5 entry the same image and core model wording as Tinefiy’s 6, 7, 7.5 and 10 entries. That supports a size comparison, not five independent footwear recommendations. It does not prove the current retailer groups all five under one selectable parent listing. Review the item remaining in the cart after any size change.
When length fits but the front does not
Try the correct work sock and notice pressure along the sides of the cap as well as at the end. Moving to a longer shoe may introduce heel movement without resolving a tapered front. A different shape can be the more useful comparison. Comfortable and safety are title descriptions; this listing does not establish a specific protection standard, measured shoe mass or a universal fit outcome.
