I had the same issue with my Sidi Way Rain Sport boots. There does not appear to be extra padding in the shift area of the boot. After six months, I sent pictures and an e-mail to MotoNation and they sent me a free pair of replacement boots under warranty. You may want to try that.Bought a pair of Sidi Way Rain boots 2 months ago and I am 1/2 way through the shift pad on the boot. Next time I will buy leather.
I've been wearing a pair of those all day long almost daily for a year now. Very comfortable once broken in, still very waterproof after 10k riding miles and countless walking miles. I've literally walked miles through the snow in them last winter, as well. I did buy a pair of memory foam cushion insoles, since I walk so much in them.
Bike boots are not so much a fashion statement as a safety item, a friend of mine
had a bad OFF, his ankle rotated, and needed a major medical operations, so I would look
for a boot with ankle support, plus if you are doing alot of riding summer and winter,
warmth, waterproof (nothing worst than COLD wet feet).
Also boots that have some sort padding on left boot for gear change duties.
