Holder size for ribcore 100k 6.5 W

[ProfessorBarDownski 9]

I’m looking to snatch a pair of retail 100ks but that size is an intermediate size in ccm. What’s the difference between int and sr ? I currently use a pair of total custom ft4 pros but I just want to try out the feel of a softer boot and see how it works for me. What’s the holder size for 6.5 W retail 100k? My ft4 holders are size 255

I have 246 on my 100k size 5.5W

So I’d think 255 would be on 6.5W
