Orthotics Innersoles ordered & Neckrest Modification

As a person with a high arch I am sometimes plagued with foot pain. Cycling does not help as I am putting constant pressure on the pedals. Normal Orthotics  are to large for use in cycling shoes as they are tight fitting. I did some research and have seen forum posts about Spenco RX Thin sole Orthotics. The retail price for these heat shaped innersoles is $29.99 plus shipping, and I bought my size on EBay for $15.00 including shipping.  I am hopping I can mold these using the oven or boiling water as I do not have a heat gun. Below is a photo of the innersoles.

 

Today I was looking over my neckrest mount after having a conversation with krispysteve from BentRiderOnline. I have decided I wanted a little stronger mount system, as there seems to be a little lateral movement at certain times.  Steve recommended that I buy a Topeak BarXtender as it has a solid center bar. I took a chance and ordered one, but I am hoping that the tubular bar that supports the neckrest will be long enough. Looking at a photo it is hard to judge actual size. Either way it is ordered and on the way. Below is the photo of the bar extended.
