Unparallel Sirius Lace Climbing Shoe
The UnParallel Sirius Lace is a highly precise and extremely aggressive climbing shoe designed for steep, hard bouldering and sport climbing. The Sirius Lace is designed by the creators of, and on the same last as, the Five Ten Dragon. It offers an improved fit and new rubber compound called 'Real Supreme', a versatile rubber which balances friction and stiffness. 3.5 mm of Real Supreme rubber yields a high level of sensitivity under the toe, whilst the medium-stiffness midsole ensures support on smaller edges and longer climbs. Being so aggressive, the Sirius Lace excels on hard, especially overhanging climbs where precision is key to success.

Real Supreme Rubber
Real Supreme is UnParallel's all-round rubber compound. It strikes the middle ground between sensitivity and stiffness and friction and durability. It's a versatile compound that can be used on every type of rock and style of climb.
• Offset lacing system allows you to dial in the perfect fit and provides extra surface area for toe hooks without sacrificing fit or function
• Lined synthetic upper provides the absolute minimum amount of stretch

Got this as an upgrade from La Sportiva Otaki, the sizing is perfect, though needs a little bit of time to get used to more aggresive fit. (Got more comfortable in couple of climbing sessions) Rubber is on the softer side, though they still edge great. Size - true to street shoe, f.e. vans - 42,5, Sirius - 42,5. (Street shoe fit is even tighter than Otaki 41.5)
Got these as I got tired of dragons changing sizing, fit and generally being impossible to get a hold off.
For me these work like a charm, they are like dragons but slightly comfier without losing precision.
I ordered size 42 and wear a 41,5 street shoe. For most la sportiva shoes I would go with 39,5 or 40.
For now I reckon they will be my primary shoe, at least until they release a super soft velcro shoe.
The rubber is super sticky! The rubber compound is more stickier than any other I have tried (Vibram xs grip2, stealth c4).
I have climbed both indoors and outdoors with these shoes for about a month and they have been performing really well.
Only downside is that I went a bit too small with these shoes. I have worn Eur 44 from Five Tens and thought it would be the perfect size from UnParallel as well. Sadly, I was wrong. I am a 44,5 in street shoe size. The break-in period has been painful and I have to take these off after 5 minutes. Also because they are synthetic material they do not stretch. So I advice to stay true to your street shoe size. This is also what UnParallel tells you.
The lacing really helps you to fit the shoe well in your feet.
Toe hooks work perfectly and there is enough rubber on the toes. Heel hooks work really good as well on bigger holds, but because I went too small on the sizing I am having problems sticking the hooks on smaller edges.
The Sirius excels on small edges and you can really feel the holds under your feet.
Before these I have tried a lot of different brands and models (La Sportiva, Tenaya, Five Ten, Scarpa) and I have to say that they really stand out in some areas (stickiness, softness) but I believe they are not going to be my go-to-shoes because of the inaccurate sizing. I am still going to keep them close by and use them on routes that need small edging and precision.
On comparison with other shoes my sizing goes
La Sportiva Skwama (Eur 42)
La Sportiva Futura (Eur 41,5)
Five Ten Hiangle (Eur 44)
Five Ten Anasazi Pro (Eur 44)
Scarpa Drago (Eur 43,5)
Tenaya Mundaki (Eur 42,6)
