## Abstract

A shoe shape selection method selects an appropriate shoe shape from a plurality of kinds of shoe shapes prepared beforehand, based on a plurality of items of data on a customer. The plurality of data items include the foot length of the customer, the foot girth of the customer and the difference between the lengths of the first and second toes of the customer.

## Claims

### Claim 1

A shoe shape selection system comprising:
inputting means, selecting means and outputting means,
wherein the inputting means inputs a plurality of items of data on a customer to the selecting means,
the selecting means selects an appropriate shoe shape from a plurality of kinds of shoe shapes prepared beforehand, based on the plurality of data items input by the inputting means, and
the outputting means outputs the result of the selection done by the selecting means,
wherein the plurality of data items include a foot length of the customer, a foot girth of the customer and a difference between lengths of first and second toes of the customer,
wherein the shoe shape selected has a larger shoe length size as the difference between the lengths of the first and second toes of the customer increases.

### Claim 2 (depends on 1)

The shoe shape selection system according to claim 1, further comprising
wherein the plurality of data items include an angle of inward inclination of a first toe,
wherein if the angle of inward inclination of the first toe of the customer is equal to or smaller than a first angle (α), an oblique type shoe tip profile is selected.

### Claim 3 (depends on 1)

The shoe shape selection system according to claim 1, further comprising
wherein the plurality of data items include a angle of inward inclination of a first toe,
wherein if the angle of inward inclination of the first toe of the customer is equal to or larger than a second angle (β), an oblique type shoe tip profile is selected.

### Claim 4 (depends on 1)

The shoe shape selection system according to claim 1, wherein if the difference between the lengths of the first and second toes of the customer is equal to or higher than a specified value, an oblique type shoe tip profile is selected.

### Claim 5 (depends on 1)

The shoe shape selection system according to claim 1, further comprising
wherein the plurality of data items include a customer having a preference of fit,
wherein if the preference of fit is medium or slightly loose, the difference between the lengths of the first and second toes of the customer is used as the plurality of data items,
wherein the shoe shape selected has a larger shoe length size as the difference between the lengths of the first and second toes of the customer increases.

### Claim 6

A shoe shape selection system comprising:
inputting means, selecting means and outputting means,
wherein the inputting means inputs a plurality of items of data on a customer to the selecting means,
the selecting means selects an appropriate shoe shape from a plurality of kinds of shoe shapes prepared beforehand, based on the plurality of data items input by the inputting means, and
the outputting means outputs the result of the selection done by the selecting means,
wherein the plurality of data items include a foot length of the customer, a foot girth of the customer and a first toe height ratio of the customer,
wherein the shoe shape selected has a larger shoe length size as the first toe height ratio of the customer increases.

### Claim 7 (depends on 6)

The shoe shape selection system according to claim 6, further comprising
wherein the plurality of data items include a angle of inward inclination of a first toe,
wherein if the angle of inward inclination of the first toe of the customer is equal to or smaller than a first angle (α), an oblique type shoe tip profile is selected.

### Claim 8 (depends on 6)

The shoe shape selection system according to claim 6, further comprising
wherein the plurality of data items include a angle of inward inclination of a first toe,
wherein if the angle of inward inclination of the first toe of the customer is equal to or larger than a second angle (β), an oblique type shoe tip profile is selected.

### Claim 9 (depends on 6)

The shoe shape selection system according to claim 6, wherein if the difference between the lengths of the first and second toes of the customer is equal to or higher than a specified value, an oblique type shoe tip profile is selected.

### Claim 10 (depends on 6)

The shoe shape selection system according to claim 6, further comprising
wherein the plurality of data items include a customer having a preference of fit,
wherein if the preference of fit is medium or slightly loose, the first toe height ratio of the customer is used as the plurality of data items,
wherein the shoe shape selected has a larger shoe length size as the first toe height ratio of the customer increases.
