20+ YEARS AND COUNTING

With over 20 years of rock shoe design and manufacturing, UnParallel Sports have had a history of producing some of the world’s best climbing footwear. In 2018 they introduce Up-Climbing to the world.

MADE IN THE USA

Based in California, UnParallel do everything in-house. From design and testing, cut and sew of materials, hand gluing and assembly, finishing and quality inspections to the final packaging of each pair of shoes.

FOCUSED ON THE BEST

Using only premium materials and industry leading high friction rubber compounds, UnParallel creates climbing shoes that are designed and engineered for improved performance.

RUBBER

Climbing is often about the smallest of details. Millimetres are often the only thing connecting you and your climbing wall, or your “interface”.

This is why selecting the rubber on your climbing shoes is so important.

Cornerstone to high performance rubber compounds is in the ‘Rubber Physical Properties’. It’s these numbers that matter. They represent the quality of a rubber. The way it feels, the way it holds under your feet and ultimately the way it will wear over time.

Durometer is a unit of measure of the deformity of a rubber compound when pressure is applied to it. It is this deformity that relates to a compounds stickiness. Too much deformity and the rubber tends to roll, or rebound, under load.

ITS THE DIFFERENCE

In other words, does it feel “gummy” or “firm”. A firm compound will hold its shape on even the smallest edge, while a gummy compound will feel like it spreads into even the smallest grains of a rocks surface.

The higher the Durometer value the more a compound that will resist compression, and ultimately, resist wear over time. While a lower Durometer value will create hightened stickiness, more roll under your load, and will have a trade off in durability for that increased performance.

It’s this juggling act of these properties that makes UnParrallel Rubber stand out. By utilising three different rubber compounds, we can best match a shoes purpose with a rubber suited to deliver that performance.

UNPARALLEL RUBBERS

VD Rubber

UP VD (Virtual Demping) has superior properties that provide unparalleled friction. Super sensitive under foot, this rubber is truly a secret weapon for anyone looking for the send. SHORE A DUROMETER: 45-55 | REBOUND: 8% | DIN ABRASION: 280

RS Rubber

UP RS (Real Supreme) is about finding the balance between the higher performance needs required for steeper overhanging lines. Super sticky, this compound has a little more roll under foot, so is better suited to climbs that are off-vertical. SHORE A DUROMETER: 65-70 | REBOUND: 11% | DIN ABRASION: 285

RH Rubber

UP RH (Real Honour) offers climbers the perfect balance between stickiness and durability. Perfect when you are looking for a rubber than can handle all terrain with unparalleled confidence in their footwork. SHORE A DUROMETER: 76-80 | REBOUND: 13% | DIN ABRASION: 290

Last Profiles

< VERTICAL A more relaxed, or flat, lasting profile with a degree of asymmetric turn towards your big toe, these shoes are more suited toward long periods spent on your feet.

 

VERTICAL With a more pronounced asymmetric turn towards your toes, placing your toes into a more compacted position, these shoes offer a more precise fit.

> VERTICAL Placing your toes into a semi crimped position provides more focus to be applied to your big toe, and ultimately allows you do deliver more downward force.

 

STEEP With a more aggressive, or cambered last, being added you can really pull on small holds, even in the steepest of terrain.

SIZING

Sizing your shoes is a critical part of being able to enjoy your climbing. Whether it’s about pushing your grades or simply enjoying a day out with friends.

Fitting your shoes needs to consider whether you’re after performance or a relaxed fit profile, and anything in between.

  • Great starting point is your street shoe size (US).
  • Try and eliminate dead space in your shoe. This should provide you with confidence on the wall, without any unwanted rolling or movement under your weight.
  • Some models come in a Womens or LV (Low Volume) options. These fit options offer a great solution if you have a narrow foot shape or heel profile, or a low arch.
  • Consider the material used in the upper of the shoe;
    • Synthetic: should meld to the shape of your foot over time, this may result in them feeling a little roomier than when you got them day 1. May up to 1/4 of a size.
    • Lined Leather: with an added second fabric backing theleather upper, these should hold their sizing a little better than leather. May move up-to 1/4 size.
    • Leather: Offer some great advantages on the foot, but you will need to factor in around 1/2 a size of movement over the first 3 months of climbing.
