... I'm still struggling with this 30 pairs of boots thing!
I do a fair number of miles... and I've been riding for well over 30 years... I tend to have winter and summer boots and, in total, I think I've had 7 pairs. I'm still using two of those (plus I have a pair of bomb proof off-road ones somewhere in the loft). While I've had all of them re-soled a few times... 30 pairs.... phew.
Currently using Altberg Hogg originals for most of the year. These are on their 2nd soles, replaced by the company. Must admit though that I quite like the added shin protection on my higher winter boot though. However, these are a good trade off with comfort on and off the bike and protection.
