Description

Comfortable shoes with ear-pulling shoe openings

Technical Field

The utility model relates to a pair of shoes, in particular to a pair of comfortable shoes with lug pulling shoe openings.

Background

As shown in fig. 1, 2 and 3, a conventional footwear includes an inner sleeve 1, an upper 2 which is worn and fixed on the inner sleeve 1, a closing-up binding ring 3, and a sole 4 fixed on the bottom of the upper 2. The inner sleeve 1 has a top opening end 101 and defines a wearing space 102, the wearing space 102 forms an inlet opening 103 surrounded by the top opening end 101, the upper 2 has a top opening end 201 corresponding to the top opening end 101 and having the same height as the top opening end 101, and the closing-up retaining ring 3 is fixedly surrounded on the top

opening ends

101, 201 to close up the

top opening ends

101, 201.

As shown in Figs. 3 and 4, since the footwear is designed to maintain the stability of the user's wearing so as to prevent the heel of the user from slipping out of the footwear, it is impossible to lower the open top end 101 of the inner case 1 too low at the ankle height of the user so as not to increase an opening width W of the fitting opening 103 too much, and thus, since the opening width W of the fitting opening 103 is actually smaller than that of a general footwear, and the inner case 1 itself has a certain structural toughness, the user cannot pull the fitting opening 103 a great deal when wearing the footwear, and thus, the angle of the user's foot fitted into the wearing space 102 of the inner case 1 through the fitting opening 103 is limited, and less than half of the foot can be fitted into the wearing space 102 at the beginning, and the user can put the sole of the foot into the wearing space 102 of the inner case 1 through the fitting opening 103 with a lot of effort Then, the user should pull the heel of the sock upward more strongly to smoothly insert the foot into the wearing space 102 of the inner case 1, which makes the sock inconvenient to wear.

In addition, in order to avoid the opening width W of the insertion opening 103 being too small, which may hinder the wearing of the footwear, the top opening end 101 of the inner cover 1 cannot be lifted too high at the ankle height of the user, which may result in poor wrapping performance of the footwear around the ankle of the user and may affect the wearing comfort.
