It time to give an update after 15 days on snow with the Redster 130 Pro.
I am so pleased with the boots on the hill. My ski buds tell me that they see improvement in my skiing and ski tracks. The liner is very comfortable to ski in all day, moderately warm. Boots are light and responsive, provide great feel for the snow. I ski with another person with the same boot, who also loves them. The only caveat is I ski a small, groomed eastern mountain and on narrow- waisted carving skis. Can't speak to big mountain crud or moguls (unfortunately for me) and, it is considered a racing boot.
I went for a fitting session, after 4 days on the boots, and with a fitter who believes all boots need some forward flex. He found that I could not flex my boots, and, I'm 6 ft. and 200 lbs. He believes a problem is friction prevents the 2nd from top strap from sliding over the upper cuff surface. He ground material off this strap and the the upper shell, but, it only improved the flex very little. I now put some silicone on the mating point surface to reduce friction, still they do not flex much. I don't have experience with other modern boots, but, they do flex about the same as my old Nordica Speedmachine 130's, maybe a little less. In any event, I don't try to flex the boot forward when skiing, I just try to tip the boot to the sides. On the hill, it does not feel rigid, but, I'm not a bump skier looking for a lot of flex. The firm forward flex helps me stay centered between the back and front of the boot, which is what I'm seeking.
Warmth / Ease of Entry
They are fine when temps are 25 degrees or so, cold toes happen when temps drop. I bought "Boot Gloves" which cover the front and that solved the warmth problem very nicely. Cold, these are trying to put on or take off. Initially, I did not use the "lace-up" liner standard in the Sidas liners and put the boots with the liner in the boots. It was a very difficult battle. I've since began to use the lace-up feature and it works so much easier. I do put silicone onto the real of the boot and the front opening to help the liner slide into the boot. And, I have to wait for them to warm up to take them off. Small price to pay for great fit and performance.
I'm using the mid-flex boot sole, will transition to the softer flex to see if that helps the boot flex a little more. I've not tried the cuff rotating adjustment, and, still wonder how a modification would help an individual skier. My fitter told me to get some video to determine how the shaft of the legs lined up, no video to date. The liners are packing out, to be expected, some minor toe discomfort has now disappeared. Still playing with adjustments to buckles. The two piece power strap, including velcro tension adjustment strap at the top, continues to baffle me in the usefulness of that design (see above).
In summary, it's been a very positive experience in my first performance fit boot. If you are in a shop that has them in stock, give it a try. From the moment I first felt the fit, I knew the future. I'm smiling.
