The Joma Sierra shoes are a trail shoe of medium high competition prepared for terrains of medium high difficulty. The upper is made of breathable and resistant nylon together with TPU in the whole central part, TPU toe cap welded to withstand blows, a back part with external reinforcements to maintain the stability in irregular surfaces. Includes Lace Pocket System: a pocket located on the tongue that allows you to store the laces. The pre-moulded EVA insole adjusted to the last of the foot, together with a 2 mm natural EVA base insole sewn to the last. The midsole is made with Full Dual Pulsor system consisting of double Phylon in different densities that adds cushioning. It features the Balance System in which a rigid plate is located between the midsole and the sole of the front part that prevents twisting and stabilizes the tread on rough terrain. The abrasion resistant rubber sole DIN-60 features a tread pattern on the front for uphill grip and rear tread for downhill grip.

Double Phylon system with different densities to optimize damping. The higher the density, the greater stability is obtained, while with lower the density, we get a lighter shoe. This technology provides the athlete with flexion and better absorption in the tread.

- Lace Pocket:
Special pocket located on the tongue that can store the laces and avoids the snagging of external elements. Used in Trail models.

- Durability:
High strength rubber that delays abrasion wear, with bidirectional studs for up and down grip.

- Protection:
Injected material that increases strength and durability in the toe.

- VTS:
Ventilation system that allows the entry of air, promotes perspiration, keeps the temperature constant, preventing foot heating.

- Glove system:
A system that is mounted between the insole and the upper part that provides greater comfort and reduces weight by resulting in a single piece. Both parts are sewn flat and without protruding seams.

- Exo Counter:
External buttress that provides greater protection and improves stability.

- Balance System:
Rigid plate between the midsole and the sole located in the front that prevents twisting and stabilizes the tread on rough terrain.

Good but watch out, the sizes are narrow
After several abrupt mountain outings, they are comfortable, but the sizes are narrow. The last would be phenomenal for people with narrow feet, but beware if you have wide feet, as they can be compressed, and it can get uncomfortable.
I haven't tried them yet.
A colleague told me that they are good
Unbeatable value for money
Very comfortable, I would recommend them
