Who is it for? The Northwave Flash TH is recommended to the road cyclists who do not have days off and are on the hunt for the following features in a bike shoe:
- Winter bike shoe with insulation
- Low-top winter bike shoes
- Cycling shoes with relatively pliable soles
What is it for? This specialized bike shoe is best suited for the following biking circumstances:
- 0 to 15°C weather
- Road rides during cold spring and autumn days
Balance between stiffness and flex. The Northwave Flash TH employs the brand's NRG Air Carbon Reinforced sole. It has a rating of 8 out of 15 in Northwave's stiffness index chart, which yields flex for comfort and a bit of rigidity for power transfer.
Replaceable rear heel pads. In road shoes, the heel pads are the first to get worn out in the soles. Hence, this pair's replaceable heel rubber pads help elongate the shoe's life and refresh the traction throughout the usage.
Ventilation holes. These holes help enhance breathability.
The Flash TH by Northwave utilizes a three-bolt cleat system. The clipless pedals that are suitable for this pair are Shimano 5800 105 SPD-SL, Time XPro 10, and Look Keo 2 Max.
The bolts are fixed in the sole, which means the users aren't offered other options to find their optimal cleat positioning.
Insulation. This bike shoe features insulation technologies to keep the foot warm and toasty in chilly weather. One of them is the Thinsulate 200g insulation, which is composed of microfibers of Thinsulate Insulation that are nearly ten times thinner than Polyester fibers.
Moreover, added thermal coating is placed on the toe area for enhanced insulation.
Protective. The heel and toe areas employ Thermoplastic Polyurethane (TPU) reinforcements to protect from abrasion and a bit of impact.
Lockdown. The shoe's upper is cinched by an SLW2 dial along nylon strings that pull everything together. This dial features a step-by-step tightening and loosening and full release as well.
Reflective. 360-degree reflective inserts are placed throughout the shoe to enhance the rider's visibility in low light conditions. This improves security and safety.
Heel retention system. The heel collar contains directional fiber that prevents any heel slippage.
The Northwave Flash TH bike shoes utilizes a GTX footbed that is crafted with four-layer aluminum material and a fleece textile on top, which yields outstanding warmth retention and insulation.
