Like most leather boots, you should expect a snug fit the first time you wear your new pair of Blundstones. To ensure you’re wearing the correct size, consider factors such as if you have wider feet, how your new boots feel on the top of the feet, and the expectation that they stretch over time. It’s also important to note that the fit of various Blundstone styles may affect what size Blundstones you wear. For example, the Classics Series comes with a pair of extra insoles to adjust fit as needed, and the chisel toe Dress Series has a longer fit than other Blundstone styles. With gradual wear, and increasing the amount of time you wear them each day during this break-in period, they will eventually mold to the shape of your foot.

Here are some ways to stretch your new pair of Blundstone boots:

• Wear them around the house. The best way to stretch your new Blundstones is to wear them around the house for short periods of time at first. This will help the leather to stretch and mold to your feet. Start by wearing them for 15-20 minutes at a time, and gradually increase the amount of time you wear them each day throughout the break-in period.
• Wear thick socks. Thick socks will help to cushion your feet and reduce the risk of blisters. Aside from cushioning your feet, thicker socks will aid in the stretching of your new boots.
• Apply leather conditioner. Leather conditioner will help to soften the leather and make it more pliable. Apply a light coat of leather conditioner to the inside and outside of your boots, and let it dry completely before wearing them.
• Use a boot stretcher. A boot stretcher will help to stretch the leather in specific areas of the boot, making it more comfortable to wear. You can buy a boot stretcher online or at most shoe stores. Bringing your boots to a professional, such as a cobbler, will also help to ensure you’re stretching your new boots as needed to mold to the shape of your feet.
• Put your boots in the freezer. This may sound strange, but it actually works. The cold air will help to compress the leather, which will create a bit of extra room in your boots. Put your boots in the freezer for 24 hours, and then let them thaw out at room temperature.
• Use a blow dryer. Point a blow dryer on the warm setting (not high heat) at the tight spots on your boots, such as the instep, for a few minutes. The heat will help to soften the leather and make it more pliable.
• Pack out the inside of your boots with newspaper. The newspaper will help to stretch the leather and make your boots more comfortable. Leave the newspaper in your boots for a few days, and then remove it.

It is important to note that, much like any other new pair of shoes, breaking in Blundstone boots takes time. You shouldn’t expect your new boots to be comfortable overnight. Frequently wearing them around the house and gradually increasing the amount of time you wear them each day, and they will eventually break in and become comfortable.

If you are still having trouble breaking in your Blundstone boots after a few weeks, you may want to consider returning them or exchanging them for the correct size. You might even consider going up a half-size for a wider fit. As a unisex Chelsea boot with sizing listed in both US and Australian, it can be confusing when purchasing your first pair of boots. The sizing guide on the Blundstone boots website provides helpful information to ensure you are buying your new shoes in the correct size.
