climbing shoes
You do not normally need to force the break in period of climbing shoes, this will happen naturally by wearing the shoes and climbing in them.
There are of course different methods for breaking in climbing shoes faster, but, they are optional and not required. Some methods could even be harmful for your shoes.
Whether your shoes need to break in or not depends on the type of shoes you bought and the size. If you bought shoes that are synthetic, don't expect any noticeable change even after 6 months of climbing in them, since synthetic shoes don't really have much of a break in period, and if they do, it's very minimal. This should also be a determining factor when buying climbing shoes, since you probably won't want to size down synthetic climbing shoes, expecting them to stretch.
Leather shoes, on the other hand, do stretch quite a bit, so if you bought leather shoes, and you sized down, then you should expect a break in period.
Rock climbing shoes that are too tight can potentially cause damage to your feet, some of the most common being muscle pain and bunions.
Climbing shoes should be tight and snug, but not too tight. Climbing shoes should not cut off or reduce circulation to your feet, and should not cause lasting pain even when taking them off.
Wearing climbing shoes that are too tight can also be dangerous from a usage point of view. If you fall from a route or jump down, landing on your feet, due to the stiffness of your muscles, they may not be able to absorb that impact as well as they should, which could cause damage.
The key to reducing the possibility of damage and pain is to choose climbing shoes that actually fit you and the shape of your feet.
It depends on the type of shoes and their purpose. Synthetic climbing shoes may stretch up to half a size, and even that is not very common. Usually, there is no noticeable break in difference with synthetic shoes, which means that if you go down a size in them, and they are very tight and painful, that may be how they will always be.
Leather shoes, on the other hand, do tend to stretch, and can even stretch up to 2 whole sizes, some even say more. Because of this, many climbers go down even 2 sizes.
It's normal and quite common for new climbing shoes to hurt a little bit. With that said, they should not cause throbbing pain that lasts after you take them off.
Depending on the type of shoes and their material, new climbing shoes usually have a break in period, which can take a few climbing sessions to get through. During this break in period, your shoes will start to change in shape and fit, molding themselves to your feet. This process can be very uncomfortable and a little bit painful, depending on the size you bought.
Keep in mind that this break in period varies depending on the type of climbing shoe, the material it is made of, and the size of the shoe. Synthetic shoes may stretch at the most half a size, while leather shoes can stretch up to 2 whole sizes.
If your shoes are synthetic, and they are causing you pain, keep in mind that they may not actually have a very noticeable break in period, which means they may just not be right for you. You may also not be used to wearing climbing shoes that are tight, which also takes time to get used to.
Because leaving them on in between routes can end up being painful, shortening your climbing session, and making every attempt on the route more and more painful and less efficient.
Taking your shoes off in between routes lets your feet rest a little bit.
Take care of them and take care of your feet.
Make sure you let your shoes dry after climbing sessions, and don't put them in your bag. Also make sure your feet are clean before putting them on.
