Velcro lacing systems aim to combine the customized fit of a lacer with the ability to gear up quickly like a slipper. In comparison to multi velcros they provide a more flexible solution with adjustable pressure points, but tend to wear down quicker.

Leather uppers made from unlined suede stretch around a full size (+- half a size). Though they might feel a little uneasy in the beginning the advantage is a higher comfort after the break in period due to conforming better to your unique foot shape. Naturally they come with higher breathability that helps preventing aggressive smells and keeping your feet cooler in hot weather.

Climbing shoes without a toe pad give your foot more space and comfort since the outer material can stretch better and adjust to your foot. If the intended climbing style or the skill level simply does not require toe hooking a lot, a toe pad becomes unnecessary but also the shoe more affordable.

Lined suede will stretch only around half a size, depending on the sizing even a little more. While the lining adds to keeping the shape of the shoe and providing a tiny bit more comfort, it also adds material between your foot and the rock. This leads to slightly less precision and potentially the development of an odor over time.

Some shoes also come with partial lining e.g. in the toe box only to reduce the stretch selectively. The advantage compared to fully lined suede might be costs and still better breathability and comfort in the rest of the shoe.

A flat profile grants most comfort by keeping the foot in its natural shape. This is an advantage for less steep routes, multi pitches and beginner climbers. Having straight toes lets the shoe slide easier into cracks for better foot jams. These shoes can also provide the highest amount of rubber to create friction on positive featureless rock i.e. smearing on slabs.

A straight shape distributes the load from the front to the whole shoe. This results in a higher support of your foot and preventing the muscles to tire quickly. This is beneficial for a long day at the crag and climbers who do not have developed strong foot muscles yet.

You can easily compare this to the different grips you are using for climbing holds: the lower the angle the more surface area you can connect and the more friction you can create. Think of gripping a sloper with the full hand, compared to smearing a big part of the sole onto the wall.

This also holds true for smaller features where you crimp up your fingers with a higher angle to create more stability in the grip. Now think of high angled toes within the shoe giving you the ability to stand on really small footholds.

The more tension is provided the more stability you have within the shoe. This increases the ability to put more pressure onto smaller footholds and keeps your foot in place while toe and heel hooking. A shoe with less pre-tension offers more comfort throughout the day and feels more natural for beginner climbers.

How much pre-tension a shoe offers can often be seen at the angle of the heelband towards the sole. Higher tension can also be created with the use of a stronger rubber. This might be indicated e.g. with dots at the back of the shoe.

A good mixture between flexibility and support are medium hard rubbers. These compounds offer good edging capabilities as well as enough adaptability to place a bigger area of the soles on the rock for smearing. The hardness and thickness of the rubber also plays a role for the sensitivity. The thinner and softer the rubber, the easier you can feel small footholds.

If and where the midsole is placed plays a major role in the support and sturdiness of the climbing shoe. It creates a platform where you can place your foot on and distribute the pressure from the point of contact to a bigger surface.

Most commonly the midsole starts in the toe box and might be as small as just an insert to support the toes up to a layer of fabric for the whole length of the shoe. Whereas it increases support it also logically lowers the flexibility at the same time making it harder to bend the shoe for smearing. This additional fabric also adds a thin layer between your foot and the rock reducing the ability to feel smaller features.
