Climbers Point

Climbers wear small sized shoes because climbing shoes are meant to be very minimal and snug. When climbers wear climbing shoes that are slightly smaller than their actual shoe size, these attributes are slightly enhanced, as is the performance a climber can gain from wearing smaller climbing shoes.

This can be a double-edged sword, though. If a climber wears climbing shoes that are too small, they may not gain any of the benefits climbing shoes provide, and may actually worsen their performance, not to mention injure or damage their feet.

Finding the right climbing shoes and the right size are not as simple as some may think. It takes going through a few shoes and trying new ones out until you find the right pair for you.

Your toes should be slightly curled inside the shoes, though, this depends on how aggressive the shoes are, the size of the shoes, and the shape of them.

If you have wide feet, you should try to find shoes that are wider and have a wider toe box. If you have narrower feet, you should find shoes that fit a narrow foot shape. This all makes a difference in how your foot will look and feel inside the shoes.

Climbing shoes should be snug enough to not have dead space in them, but not so snug that you feel throbbing pain and can't even walk or climb in them.

Climbing shoes are designed for being snug and minimal to help with footwork, this includes standing on tiny holds, and pulling your weight with your feet. If your climbing shoes are not snug and tight enough, your feet may move inside of them, which can make it much more difficult to pull your weight and stand on small holds.

Listen to your body and your feet, if it's too painful, go up a size or find different shoes that fit your feet. Having extremely tight shoes is not the answer if it reduces your performance.

Climbing shoes should be snug, with as little to no dead space in them as possible. They should not be painful though. Slight pain when they are new is normal, but pain that lasts even after their break in period and after you take them off is not supposed to happen.

If you want to clean your climbing shoes by brushing them, make sure the brush won't damage your shoes. Using wire brushes or steel brushes could damage the fabric, rubber, and other materials used in the climbing shoes.

For most situations, a damp cloth is enough to clean climbing shoes very well, but if you have something a little bit more stubborn, a climbing brush could also do the trick.

Climbing doesn't really target your chest muscles that much. There are situations in which you will need to push your weight up with your hands, which will utilize your chest muscles, but not really to the point where it will strengthen them that much.

It's best to supplement your climbing with chest targeted exercises, such as the bench press, so that when you get to climbing moves that you need to push your body up, you will have the strength to do it.

If climbing is a sport that you enjoy and are motivated by and it causes you to change your habits and exercise more, then yes, climbing can be a great way to help you lose weight.

Exercise in general is a great way to help you lose weight, but it really comes down largely to your diet. With that said, if you reduce your calorie intake but are not active at all, the journey is going to be less efficient. So both aspects really go together.

Which brings me to my first point. If climbing motivates you to change your habits, improve your lifestyle, eat healthier, and exercise more, then yes, climbing can very much help you lose weight.

I don't know his actual connection to the sport or its origin, but, from the very few videos of him climbing and talking about it, you can see how much he loves the sport.
