this is my impression. back when i still was in academia it would pop up from time to time but i never published there since i never cited any of their journals in the first place. (why would one publish there when all your peers are somewhere else). nowadays i sometimes get requests from them to my personal email for special issues which i just ignore. (it’s academic spam essentially).

have a look at retraction watch https://retractionwatch.com/?s=mdpi

maybe try grundstoff.net (German company). their stuff is rather plain but t-shirts are available in very heavy fabric. i like them but I’m not sure whether it’s any good for when you work out (i sweat a lot when I’m skating).

thanks for the tip. I’ll have a look at what they have

Okay, now its getting ridiculous. Just measured the leg opening of my current pair, its 17’'.

Browsing through their website, i noticed, that leg opening appear to vary with color, approx. 1". Then i thought, maybe, i try my luck in different european stored (spain, belgium, netherlands). Same pattern, but then i noticed that i still had a tab for the US store open. Apparently, fit also differ between countries.

E.g. 501 Style # 005013411 in the US

How it Fits

Regular Through The Thigh
Sits At Your Waist
Straight Leg
Front rise: 11 1/4",Knee: 17 1/2",Leg opening: 16",Measurements based on size 32

in Spain

How it Fits

501
Sits At Your Waist
Straight Leg
Front rise: 12 1/4''
Knee: 18 5/8''
Leg opening: 17''
Measurements based on size 32

I just want a pair of jeans ffs

thanks for your reply. the thing is: all 501 100% cotton i tried have a smallish leg opening although they are called “straight leg”. these work fine when worn with shoes but sit too high when worn with biker boots. the ones i try to find again have a wide enough leg opening to fit the boots and rest in the heel. it’s really weird. and they really are 501 not boot cut, i swear

some might regard it as a predatory publisher

thank you for your work. although i don’t post here i really appreciate the community and the work that involves. thanks a lot
