@Ikeaparty Hi man, to confirm you don't need to wash/soak these prior to wearing, however some do choose to in order to remove all shrinkage prior to wearing so people know what they are working with through wear. Totally personal preference whether to wash/soak prior to initially wearing. The inseam is expected to shrink approximately 1.0" with this first wash/soak, however if you are worried about too much shrinkage, I would perhaps suggest cold/hand soak as shrinkage is determined by heat and agitation of said soak and doing so will give you a greater chance of lessening any inseam shrinkage.
I hope this helps, but if you have any further questions just shout us on here or email us at: shop@ironheart.co.uk
