Based on the recommendations primary from this newsgroup, I went ahead and purchased a pair of Shoespring shoes
The first thing I should say about Shoespring shoes is this: Whatever size you wear, you may need to increase that by a full size (1.0 in US units). The first pair I got from Shoespring were way too small. I've since traded them off for a pair 0.5 US units larger, and they are still a little too small. Specifically, they're a bit narrow. (Lengthwise, they seem to be right on target, because I now have essentially too much length on the interior.) Shoespring says they do not currently offer any wide models, which is what I suppose I would need to acquire in order to counter the narrow trend of their make.
I've decided to deal with the too-narrow shoes I currently possess (the second pair I got from them), because the whole ship-shoes-back, wait-for- replacement thing has gotten old. I have discovered that I can remove the built-in insoles from the shoes, with the result that they suddenly fit remarkably well. But obviously, this would probably prove to be a catastrophic decision if I were to actually wear the shoes like that to work, all day long. Springs or no springs.
Therefore, I'm needing to get some information on purchasable insoles. The built-in insoles are too thick. I suspect there are some gel-based solutions out there which would be not so thick, and would serve my purposes handily. What I DON'T know is whether or not it would be a good idea to outright replace the built-in insoles with gel substitutes. Is that what is normally done? Or do people more typically use both insoles simultaneously?
Further along this train of thought.. What are some good gel insoles? I picked up some Bob's Insoles (not the actual name of the product) from Famous Footware or somesuch, for about three bucks. They are clearly a very minimalist product and will probably not last more than a month or two of wear. This indicates to me that there is bound to be a wide variety of qualities when it comes to these products. Just about anyone out there would be more knowledgable than I am on this subject. Recommendations would be most welcome. Particularly, I'm hoping to find some insoles which are FLAT. The Shoespring built-in insoles are actually a little thicker on the heels, and even my preliminary tests have indicated that this will generate a lot of fatigue in my heels.
Thanks in advance!
