What Sizeer does

Sizeer is a multi-brand sneaker and streetwear retailer operating an omni-channel business across Central and Eastern Europe as a brand of Marketing Investment Group S.A., a privately held diversified group headquartered in Kraków, Poland. The company sells footwear, apparel, and accessories from more than 40 brands, including Nike, adidas, New Balance, Puma, Vans, Converse, Jordan, Birkenstock, UGG, and Salomon, through three integrated channels: an e-commerce storefront (sklep.sizeer.com), a mobile application (SizeerApp on iOS and Android), and a network of over 115 brick-and-mortar stores across nine countries (Poland, Czech Republic, Hungary, Lithuania, Latvia, Romania, Serbia, and Slovakia). Customer segments are organized horizontally across Men, Women, and Children, with seasonal Back-to-School campaigns targeting the youth and family cohort.

The technology stack combines a standard e-commerce platform with a proprietary loyalty layer (SizeerClub), which integrates points accumulation (1 point per 1 PLN spent), a 250-point registration bonus, a 30 PLN welcome coupon, member-only free delivery, and wishlist functionality across online and offline channels. Distribution is supported by a third-party fulfillment partner (myBox Logistics, operating a distribution center in Chęciny) and multi-carrier last-mile delivery through DHL, InPost Paczkomaty, DPD Pickup, and ORLEN Paczka. Payment infrastructure spans card networks (Visa, Mastercard), digital wallets (PayPal), Polish gateways (Przelewy24, BLIK), and BNPL providers (Klarna, PayPo).

The business model is predominantly transactional retail with two principal revenue streams (online sales and physical store sales) and a loyalty-driven retention loop. Pricing follows unit pricing on individual SKUs with promotional bundles (for example, two T-shirts for 179.99 PLN, three for 219.99 PLN) and mid-season sale mechanics; standard free shipping applies above 350 PLN, while SizeerClub members receive unconditional free delivery. Reported operational metrics include a 1-5 business day fulfillment window, a 30-day return policy (above the statutory 14 days), and a 4.9/5.0 customer rating across 6,802 TrustMate reviews.

Recent moves6 records

Expansion highlights5 records

Emerging players

• ASOS: Global online fashion retailer with strong 20-something customer overlap with Sizeer. Competes in the same sneakers-and-streetwear category, but lacks a physical store presence, making Sizeer's omnichannel model a differentiator.

Broad incumbents

• JD Sports: Leading European multi-brand sports and streetwear retailer with extensive physical and online presence. Comparable to Sizeer in product categories (sneakers, apparel, accessories) and customer segments, with a strong position in premium athletic brands.
• Zalando: Leading European online fashion platform with a major footwear and streetwear category. Competes with Sizeer's e-commerce channel on assortment and convenience, especially in Poland and other CEE markets where it has invested heavily in logistics infrastructure.
• Deichmann: Europe's largest shoe retailer, operating thousands of stores across the continent. Comparable to Sizeer in core footwear retail focus and CEE presence, with a broader price-positioned assortment including family and value-oriented footwear.
• Snipes: Global sneaker and streetwear multi-brand retailer with strong European presence. Directly comparable to Sizeer in product mix (sneakers, apparel, accessories from Nike, adidas, Jordan) and target demographic (youth/streetwear consumers), but operates at significantly larger scale with stores across Western and Central Europe.
• Foot Locker: Global multi-brand athletic footwear and apparel retailer. Closely comparable to Sizeer in product mix (Nike, adidas, Jordan, New Balance) and target customer, but operates at much larger scale and competes directly in Polish and select European CEE markets.

Direct peers

• CCC: Poland's largest footwear retailer, headquartered in Polkowice. Direct competitor to Sizeer across Polish cities with omni-channel operations supplementing traditional footwear assortment with casual and streetwear styles.
• Eobuwie (Modivo): Polish-headquartered online shoe and fashion retailer (part of Modivo Group). Direct competitor to Sizeer in the Polish footwear market, with comparable brand mix (premium and casual sneakers) and strong loyalty program; closely matched in scale and customer overlap.
• Office Shoes: Multi-brand sneaker and fashion footwear retailer with stores in UK and parts of Europe. Comparable to Sizeer in product mix (Nike, adidas, Converse, Vans) and youth-oriented positioning, though primarily focused in Western European markets.

Regional players

• Empik (with fashion offering): Polish multi-category retailer that has expanded into fashion and footwear. Comparable to Sizeer in serving Polish consumers with branded lifestyle goods, though footwear is a smaller part of its broader assortment.
