Although can get pricey over time, get a heavy set girlfriend or wife to sit on back squatting the back end down that extra 1-2" needed. Although, can get tipsy if loaded down at some uneven stops.

Since just 2" shorter than me at 5'10" and near 1/2 the weight, I'd lower your shock settings to 2 or 3 vs. mine maxed out on OEM Valk I/S shocks and/or buy a shorter set of rear shocks.
Then again, your taller shoes are the cheapest route if they work out/are sturdy and don't twist an ankle or anything.
