could you please compare 238 last with other c&j lasts? 337 and 240 fit me quite snug, but not uncomfortably tight. 318, 325 and 360 are OK, perhaps a bit roomy. 324 is unbearably narrow for me. I am aware that 238 is known as a narrow C&J last but I don't know whether it is very narrow. Is it even narrower than 348 and even 324?
