Once upon a time, the neoprene boot (or bootie in surfer parlance) was as basic a piece of footwear as you could get, with the exception, of course, being the flip-flop. But with Sperry Top-Sider's latest offering into the dinghy boot market, that's clearly not the case any more. Through its collaboration with the U.S. Sailing Team, Sperry Top-Sider has developed the Submersible Boot. This seemed the ideal kind of boot for dinghy or small (wet) keelboat sailing, so I brought a pair with me to Acura Key West Race Week last month, curious how they'd fare on a bigger keelboat, and in the heat of the tropics.
