Just received a pair of the Danner Sharptails; sent back first pair as I should have read reviews about upsizing. Re-ordered my normal size in wide and can get on an off with out "too" much extra effort. Typical of most slip ons. Had already sent back a pair of the lace up/zip up Pronghorns; they were VERY uncomfortable. The leather above the ankle bent inwards and were flat painful.
The Sharptails feel much lighter on foot than I would have expected. Going to wear them around the house for couple of days; hard to beat Danner's free shipping and free returns policy. You can actually return a boot up to a year if never worn outside
