Blue Sole insoles have about as high of an arch as you can get.Interesting, I need a taller boot than the Cevedale and also want full grain leather. I played with a set of L&S inserts too and, while the cushioning is nice, decided they were not for me. After bouts with plantar fasciatis, I need arch support. I'd love to see an insert with the arch support of Superfeet or similar, and the cushioning and volume filling capability of the L&S.
I talked to L&S as well. Told them I really like the Quest 4 D's and they also recommended the Cevedale. I bought the Cevedale and found them a bit narrow in the forefoot. Definitely not as wide as the 4Ds. I sent them back and they stretched them for me. At first, it didn't seem like it helped, but I figured out if I isolate the forefoot lacing from the ankle lacing with a surgeons type knot and left my fore foot loose, then I don't have any narrow pressure issues and find the boots quite comfortable, especially with the Synergy insoles.. I am still getting heel slip/blisters though, even with a pair of liner socks. But, now that I've found Leukotape, I really don't care anymore about heel slip. I've never had a pair of boots that didn't cause blisters and I've resigned myself to the fact that I simply have to tape up before I hike. With the Leukotape and Synergy footbeds, my feet are quite comfortable in these boots, even at the end of a long ruck. They are a very stiff boot and will provide plenty of support under a heavy load. So, make sure you give yourself enough time and mileage to break them in properly.
If your still skeptical, then before you wear them outside and void the return policy, take your ruck to a gym and get on a treadmill for an hour and see how they feel. I think you have 15 days to return them if you don't like them as long as they are in like new condition.
Good luck. I know how frustrating it can be!!!
Back to the drawing board here. Scarpa Wrangells were really well made but really stiff and I got cheese grater like heel slip in them. They went back. Lowa Tibets were almost perfect. They felt awesome out of the box and I thought I'd found love. Until I went on some real hikes with a pack. They are just a bit too narrow on the outside left forefoot and gave me a painful pressure point.
So I gave up trying to do this myself. I hate trial and error. Talked to Lathrop and Sons and they were pushing the Cevedale Tech Lite. I took pics of my feet standing in insoles (from my Quest 4 D's, which fit perfect, I just need more boot) and they recommended the Cevedale TL in a 1/2 larger than my normal 10.5. With their foot beds, custom fit. I'm skeptical, but I told em to go ahead. Thoughts?
Well I got the Cevedales from L&S today. I must say, I knew I should have trusted my gut. They aren't gonna work. They are too long in an 11 and just too narrow. I can feel the same pressure point on my left forefoot as I did with the Tibets. They might break in some and get better, but I am not going to risk it after paying nearly $500, especially with a 15 day return policy. Back they go, and back to the drawing board I go! I hate this!
