Redback Boots Sizing: How Half Sizes Really Work Part 3

Redback Boots Sizing: How Half Sizes Really Work Part 3

For many US shoppers, going up half a size means a slightly longer shoe. With Redback boots, that assumption can lead to the wrong choice.

A half size does not always add length

In conventional footwear, including many cement-construction shoes, a half-size step normally adds length as well as some width. Redback’s direct-injected boots work differently: a half size is essentially the same length as the corresponding full size, with more width, instep room and internal volume.

For example, Redback AU/UK 8 and 8.5 are essentially the same length; 8.5 provides a roomier fit. This is a Redback sizing characteristic, not a rule for every boot or construction method.

Check the AU/UK size first

Redback boots use Australian/UK sizing. For US men’s sizes, the usual starting point is one size down: US 10 generally corresponds to Redback AU/UK 9. Use this as a reference and check the particular model and fit. Do not apply the men’s conversion directly to US women’s sizes.

Great Barrier / UNPU: when the instep matters

The Redback Great Barrier / UNPU, known as Nevada in Australia, is a useful example. In our fitting experience, its lower, snugger instep can suit a low-instep or lower-volume foot.

A customer with a high instep may feel pressure across the top of the foot and assume the boot runs small. The issue may be instep volume rather than length.

For customers with a high instep, another similar Redback style, such as the UBBK or UBOK, may therefore be more suitable. Compare the model’s fit rather than automatically choosing a longer size.
