K2 Skate Redline 125 C Racing Inline Skates

Son muy bonitos , pero incómodos y tuve que hacer la devolución por qué me enviaron una talla distinta a la que pedí

Those skates are for high quality asphalt surfaces, even small roughness of the surface transfers very harshly to the foot. I replaced the wheels to softer 85a hardness and they feel much more comfortable on not ideal asphalt. The boot itself fits me well and I find it quite comfortable on smooth surface. The wheels and bearings are very fast. Rolling is extremely efficient. I suggest a second softer set of wheels for more comfort.

Cool skates wish didn’t come damage , had send back

Great design, fit and overall engineering ingenuity. Carbon fiber structure and a very rigid light frame. But a major design flaw has the middle wheel rubbing against the carbon fiber. Apparently this is a recurring flaw, as I found out on a separate review. Had to return them After first trial run. Can’t wait for K2 to address this issue on a future iterance.

I have owned nearly every marathon skate on the market and the K2 Redline are easily my favorite. They are the most comfortable skate I've ever used and allow for correct body positioning because of the flexible pivoting cuff. I consider this the best skate for marathon skating and learning to speed skate. The K2 design is essentially a speed skate with additional lateral support without interfering with knee pend and correct body position. It's truly a one-of-a-kind skate, and one that I feel is underappreciated. The boot is flexible and lacks some lateral support in the toe and midfoot area of the boot when compared to a speed skate, however the heal and cuff make up for this. The boot is not heat-moldable but the flexible boot allows for a comfortable and tight fit. These boots do not have the energy transfer of a true speed skate, but the K2 Redline does perform excellently for it's target audience - the advanced fitness skater and intermediate marathon skater (or aging advanced marathon skater who lacks adequate ankle strength). The best quality of this skate - aside from it's futurist look - is that I can skate for hours and never do I feel any fatigue or ache in my lower back. The K2 Redline allows for correct ankle bend - which creates correct knee, hip, pelvis and back bend. My other marathon skates have higher cuffs. Even when I loosen my top laces and press my shin into the tongue of these other skates, I will experience lower back discomfort. My K2 Redline will tire out my quads (just like a speed skate) while my other skates will tire out my lower back. If you are looking for an advanced fitness skate or marathon skate and need more support than a speed skate, these K2 Redline are easily the best choice. My hope is that K2 will release a Redline Pro - which is a nearly identical design with a heat moldable foot with more carbon fiber in the toe and side foot areas, and straps that have buckles to allow for better tension. Stick with the same fabric straps just adjust the design for better tension. Everything else is perfect. I have owned the Bont Semi Race 3, Powerslide Arise RD 110, Powerslide R6, Rollerblade Maxxum 3WD 125, Seba Marathon, Bont Jet, Rollerblade Tempest, Rollerblade Racemachine LE, and a few others.

The wheels rubb the bottom of the boot. I wrote K2 warrant they never responded. I’ve had 20 pairs over the years. So I put in washeer spacers myself .

So disappointed to see malfunction of middle wheel in this much expensive skates… I’ll recommend k2 110
